- Electronic Newsgroups and Mailing Lists
- =======================================
-
- Newsgroups
- ++++++++++
-
- rec.sport.golf is a newsgroup which discusses ANY subject as it
- pertains to golf. For those people interested in the rules of golf,
- handicapping procedures, golf equipment, swing techniques, or you just
- want some information on golf courses across the globe this is the
- place you want to be.
-
- Mailing Lists
- +++++++++++++
-
- GOLF-L@UBVM.CC.BUFFALO.EDU is a mailing list which has a gateway to the
- rec.sport.golf newsgroup. This means that messages sent to the mailing
- list will show up in rec.sport.golf, and messages posted to
- rec.sport.golf will pass through the mailing list. So for those of you
- that can't access USENET, you can still have access to all of the
- information posted to rec.sport.golf.
-
- In order to be placed on the mailing list, you will have to send a mail
- message to LISTSERV@UBVM.CC.BUFFALO.EDU. The body of the message should
- contain the following command...
-
- SUBSCRIBE GOLF-L Greg Norman (use your name instead of Greg Norman)
-
- You should receive a message within a few hours from Listserv asking
- you to confirm your subscription. You must then follow the instructions
- and confirm your subscription within 48 hrs. or the command will be
- cancelled. After the subscription is confirmed, you will be added to
- the list.
-
- For help or more information regarding the Mailing List, send a message to
- CTANSKI@ONONDAGA.BITNET (owner of GOLF-L).
-
-
-
- List of Golf Archives
- ======================
-
- An archive consisting of information related to golf is being kept on
- dunkin.Princeton.EDU.
-
- The "articles" deal with things ranging from handicapping systems and
- programs, to club making and design, and even a few GIFs of various
- courses.
-
- The files in this archive are available by mail server, anonymous FTP,
- Gopher, and WWW on dunkin.Princeton.EDU.
-
- If there is any information you would like to see placed in the
- archives, either drop them off via Anonymous FTP on
- dunkin.Princeton.EDU, or send them via mail to
- marcelo@dunkin.Princeton.EDU.
-
- Mail Server
- +++++++++++
-
- ** NOTE - The Mail Server has moved from marcelo.remote.Princeton.EDU to
- dunkin.Princeton.EDU. **
-
- There lives a mail server that will get files from the archive and mail
- them to you. If you send mail to listproc@dunkin.Princeton.EDU, with
- the commands in the body of the message, you should receive the files
- via mail within a few days (usually the same day).
-
- So for example if you wanted the clubdesn.0 article, you would send
- mail to listproc@dunkin.Princeton.EDU with a line in the body which
- looks like this...
-
- get golf clubdesn.0
-
- You can retrieve several files at the same time by adding the commands
- on separate lines like so...
-
- get golf clubdesn.0
- get golf clubdesn.1
- get golf clubdesn.2
- get golf clubdesn.3
-
- If you need any more help, you can send a message to the mail server (
- listproc@dunkin.Princeton.EDU) with the message of "help" (without the
- quotes), or send mail to marcelo@dunkin.Princeton.EDU.
-
- Anonymous FTP
- +++++++++++++
-
- ** Please note that anonymous FTP has moved from
- marcelo.remote.Princeton.EDU to dunkin.Princeton.EDU (128.112.64.39). **
-
- The golf archive is also accessible via anonymous FTP on dunkin.Princeton.EDU
- (128.112.64.39).
-
- For those of you unfamiliar with anonymous ftp, here is an anonymous
- ftp session to help guide you. I recommend looking through the
- news.answers and news.announce.newusers news groups for further
- information.

- General Golf Club Information
- =============================
-
- What is a WOOD/IRON
- +++++++++++++++++++
-
- The WOOD
- Historically the "wood" was made of wood (hence the name), but they
- now come in a variety materials. They are also generally "bigger",
- in terms of size, than other clubs. "Woods" are typically long
- distance clubs meant to be used when distance is more important than
- accuracy. A driver is usually a '1' wood with somewhere between 8
- and 12 degrees of loft (0 degrees of loft would be perpendicular to
- the ground).
- The IRON
- Irons were originally made using "iron", but are now genarally made
- from steel. "Irons" are smaller than "woods", and are considered to
- be "finess" clubs, meant to be used when accuracy is needed rather
- than distance.
-
- What does the number on the club mean
- +++++++++++++++++++++++++++++++++++++
-
- For the most part, the number "represents" the loft of a club. The
- lower the number, the lower the loft. The lower loft will result in
- greater distance with a loss of accuracy. This also equates to lower
- numbered clubs being more difficult to hit.
-
- What makes a "set" of clubs
- +++++++++++++++++++++++++++
-
- A "set" of golf clubs is restricted to no more than 14 clubs. What
- constitutes this "set" depends on your preferences.
-
- In general, a "set" will include the following clubs:
-
- Irons:
- 3, 4, 5, 6, 7, 8, 9, PW
- Woods:
- 1, 3, 5
- and a putter
-
- This is not to say you have to carry all of these clubs. For example, a
- beginner may carry a Driver (1 wood) or 3 wood, a 3, 5, 7, and 9 iron,
- as well as a putter.
-
-
-
- Types of Golf Balls
- ===================
-
- Balata vs Surlyn
- ++++++++++++++++
-
- Balata and Surlyn are ball-covering materials. But there are typically
- other differences between balata and surlyn balls besides the cover.
-
- Balata
- ++++++
-
- A balata covered ball is typically a three-piece ball: a core wound
- with rubber and covered with balata. There has been a lot of discussion
- as to what "balata" is. Let's just say that balata is a soft substance
- which leads to cuts and nicks. This "softness" is said to offer "better
- playability" which is to say that the golfer can "shape" his/her shot
- (fade/draw), and get more "action" (backspin) on the greens.
-
- Surlyn
- ++++++
-
- A surlyn covered ball is typically a two-piece ball: a solid core with
- the surlyn cover. Surlyn is a man made "uncuttable" substance which is
- designed to eliminate the cuts and nicks. The drawbacks of the harder
- ball are that it is more difficult to "shape" his/her shot (fade/draw),
- and get "action" (backspin) on the greens.
-
- Quick Comparison
- ++++++++++++++++
-
- ** Balata **
- 1. Softer cover
- o Better spin
- o scuffs and cuts easily
- 2. "Works" the ball better because of spin (Draw, fade, backspin)
- 3. Usually three-piece ball (Liquid-filled core, wound rubber, and
- cover)
- 4. Usually more expensive:
- o Higher first cost
- o Shorter life
- ** Surlyn **
- 1. Harder cover
- o Not as much spin
- o resists scuffs and cuts
- 2. More distance
- 3. Usually two-piece ball (Solid core and cover)
- 4. Usually less expensive:
- o Lower first cost
- o Longer life
-
- Compression
- ++++++++++++
-
- Compression of a golf ball is designed to give more "feel" with lower
- compression, and more distance with higher compression. Typical
- compression ratings are between 80 and 100, with most players using a
- 90 compression ball as a compromise. While neither the distance issue
- or "feel" issue has ever been proven, above average golfers tend to
- agree that hitting a 100 compression ball feels like "hitting a rock".
-
- Notes
- +++++
-
- Now what you really want to know: Determining the type of ball you
- should use, as well as the compression is purely preference. Some
- people find that a surlyn covered ball is quite playable, while others
- feel they need the "action" a balata ball gives. I generally play
- whatever ball I find while searching for the ball I lost, but then
- again I'm not on the PGA tour.
-
-
-
- Types of Irons
- ==============
-
- Investment Cast
- +++++++++++++++
-
- A "positive" or master model of the clubhead is made, usually made of
- aluminum, which contains all engraved markings, scoring lines, and even
- the hosel hole. Wax is injected into the master, which yields a
- positive "wax" clubhead. The clubhead is then dipped into ceramic
- several times to produce the negative mold. The wax is then melted, and
- stainless steel poured into the ceramic mold. When the ceramic casting
- is removed, you have the clubhead ready to be painted.
-
- Forged
- ++++++
-
- Forging a club is very similar to what the village blacksmith used to
- do. Dies are "sunk" or cut, by milling the desired impression, and
- forging is accomplished with a "drop hammer". The manufacturer is then
- presented with a raw forging, which is a close approximation of the
- clubhead desired. The clubhead must then be finished by milling,
- grinding and drilling.
-
- Muscleback
- ++++++++++
-
- A Muscleback iron, also known as a "blade", has generally been
- associated as a "forged" iron. While the manufacturing process isn't
- really important, the design of the clubhead is. The muscleback iron
- distributes the weight evenly throughout the entire head, producing a
- small "sweet spot" in the center of the head. This is to say that a
- shot hit in the center of the face will produce a longer, straighter
- flight trajectory. Shots which aren't hit pure (off-center) will
- produce a shorter, unpredictable flight trajectory.
-
- Cavity Back
- +++++++++++
-
- A cavity back iron, also known as perimeter weighted, has generally
- been associated as an investment cast iron. Again while the
- manufacturing process isn't really important, the design of the
- clubhead is. The cavity back iron distributes the weight around the
- perimeter of the head, producing a large "sweet spot". This makes the
- off-center shots more forgiving, flying longer and straighter, than an
- off-center shot with a muscleback iron.
-
- Quick Comparison
- ++++++++++++++++
-
- ** Investment cast **
- o Usually a Cavity back
- o Peripheral weighting
- o More forgiving
- o Stainless steel
- ** Forged **
- o Usually a Blade or Muscleback
- o Central weighting
- o Better "feel"
- o Carbon steel & chrome
-
- Notes
- +++++
-
- Now what you really want to know: When investment cast heads were first
- introduced, several companies claimed that the "feel" of the head was
- lost. These same companies also claimed it was more difficult to "work"
- the ball with the cast heads. Keep in mind that most golfers tend to
- believe that a muscleback iron (usually forged) produces more "feel"
- than the cavity back models (usually investment casted). They also say
- that it is easier to "shape" the shot using the blades over the
- perimeter weighted clubs. Before making a decision, you should try a
- few muscleback and cavity back irons and see for yourself. For more
- information please refer to Dave Tutelman's "Designing golf clubs"
- articles.
-
-
-
- Types of Woods
- ==============
-
- Wood
- ++++
-
- There are basically two types of wood used, persimmon and maple.
-
- o Solid heads are usually persimmon.
- o Laminated ("plywood") heads are usually maple.
-
- Persimmon heads are made by using a sophisticated turning machine. The
- process is much like making a duplicate key for a lock. The second, and
- most commonly used, wood is laminated maple. Generally, 1/16-inch
- veneers of maple are laminated together much like a sheet of plywood.
- Then the veneers are heated and pressurized, and finally turned like
- the persimmon heads. While many golfers indicate that they have a more
- solid feel at impact with persimmon heads, studies show no support of
- this. Other golfers prefer the laminated maple, reasoning that they
- last longer. Presently it costs roughly three times as much to use
- persimmon as it does laminated maple.
-
- Metal
- +++++
-
- Investment cast metal heads have gained popularity, mainly because of
- the added control of peripheral weighting (which was not a true design
- goal, but a product of the casting process to achieve proper weight).
- The stainless steel heads are cast hollow to restrict excessive weight,
- and usually filled with polyurethane to muffle impact noise. Metal
- "wood" heads have also been noted as adding distance to center and
- off-center shots.
-
- Graphite
- ++++++++
-
- The same material that is used for shafts is also used to make graphite
- heads. There are two subtle variances in manufacturing techniques. In
- one case, the graphite prepreg is mixed with an ABS plastic, and is
- injection molded into a head. In the second version the prepreg is
- given an epoxy base and the mixture is compression molded. Graphite
- heads are manufactured with the same weight as the wood and metal
- heads, but are generally much larger than conventional heads. This
- increases the size of the "Sweet spot". No tests yet have proven
- graphite heads to be more forgiving or longer than other materials.
-
- Oversized
- +++++++++
-
- The general consensus is that "oversized" heads, generally made of
- stainless steel or graphite, create a larger "sweet spot". This
- produces a longer and straighter flight trajectory on off-center hits.
- When using stainless steel, the walls of the head must be made thinner
- to keep the overall weight "normal" (191-205 grams for a 1 wood). This
- has caused some metal "wood" faces to "crush" or dent. For this reason,
- some manufacturers are bringing "Mid-sized" metal woods to market,
- which allows the "sweet spot" to stay large, yet keeps the walls of the
- head thick to prevent denting.
-
- Metal with Composite Face
- +++++++++++++++++++++++++
-
- In conjunction with "oversized" clubheads, manufacturers are starting
- to use "face inserts" (normally plastic, graphite or lightweight
- metals). This allows them to produced the larger sized heads without
- worrying about the face crushing or denting. This also allows them to
- keep the overall weight of the head down. Face inserts, in metal
- "woods", is a fairly new design, and tests regarding their playability
- and forgiveness have not been published.
-
- Notes
- +++++
-
- Now what you really want to know: The type of "wood" you should use can
- only be determined by what "feels right". While metal and graphite
- heads can offer forgiveness on off-center shots, some argue that you
- lose the feel you receive from true "wood" heads. Like the irons, you
- should try several before buying.
-
-
-
- Types of Shafts
- ===============
-
- I found this to be the most difficult FAQ to answer. The shaft is the
- most complex piece of a golf club, and probably the most important.
- With varying degrees of flex, flex locations, weight, length,
- materials, torque, etc., an article devoted entirely to the shaft is
- needed, but not available. I'll do my best to answer some of the
- questions regarding them.
-
- Steel
- +++++
-
- Steel shafts are generally made from either carbon steel or stainless
- steel. For the most part, the manufacturing process between the two are
- similar. A steel strip is rolled into a tube, and is drawn over a
- mandrel until the diameter and wall thickness are reduced to their
- exact specifications. At this point the step pattern is formed on the
- shaft. Then the walls are made thinner at the grip and thicker at the
- tip to give the shaft its flex characteristics. Then it is hardened,
- tempered, straightened and stress relieved. The final step is to polish
- and chrome plate the shaft. One of the best features of the steel shaft
- is the ability to have the same "feel" throughout the entire set. This
- means that the stiffness in the 3 iron will will be the same as the 9
- iron. Other features are its durability and price.
-
- Graphite
- ++++++++
-
- Graphite shafts are made from a graphite tape. The tape, which has an
- epoxy binder, is wrapped around a steel mandrel. The wrapped shaft is
- then temperature cured and the mandrel removed. The raw shaft is then
- sanded and cut to proper length, at which point it receives a clear or
- colored paint coating. Its most talked about feature is its light
- weight. It also helps dampen the vibration caused by clubhead impact
- with the ground. A few of the drawbacks are the "feel" of the shaft
- (some people complain that a stiff graphite shaft does not feel like a
- stiff steel shaft), the stiffness is not consistent throughout a set,
- and its price tag.
-
- Titanium
- ++++++++
-
- I have very little information regarding the titanium shaft and its
- manufacturing process. Among some of its features are its weight
- (lighter than steel), and its vibration dampening. Some complaints are
- that the shafts are too stiff, and it carries a big price.
-
- Stiffness
- +++++++++
-
- The stiffness, flex, or deflection of a shaft defines the bending
- characteristics of the tube, when a load is applied to the shaft. The
- most common shaft flexes are designated as X (extra-stiff), S (stiff),
- R (regular), A (man's flexible), or L (ladies'). For people with high
- swing speeds, it's desirable to have a stiffer shaft to keep the club
- head from lagging behind. For people with slower swing speeds, the more
- flexible shafts offer an extra "kick" at the bottom of the downswing to
- help propel the ball.
-
- Kickpoints
- ++++++++++
-
- The kickpoint, bendpoint, or flexpoint defines where the shaft will
- bend. It affects the trajectory of the shot; the higher the kickpoint,
- the lower the trajectory. The three points: High, Mid, and Low offer
- different flight trajectories: low, mid, and high respectively. For
- someone that generally hits the ball with a high shot trajectory, a
- High kickpoint is desirable in a shaft. For someone with a low shot
- trajectory, a Low kickpoint helps get the ball airborne and on a higher
- flight path.
-
- Torque
- ++++++
-
- Generally torque is a rating applied to a graphite shaft. It specifies
- the "twisting" characteristics of the shaft. The normal torque rating
- of a steel shaft is about 2.5 degrees. The general range of torque
- ratings found on graphite shafts are from 3.5 to 5.5 degrees, although
- it is possible to get shafts with lower or higher ratings. The higher
- the torque rating, the more the shaft twists for a given twisting
- force. The torque rating also seems to be tied to the stiffness of a
- shaft. The lower the torque rating, the stiffer the shaft.
-
- Notes
- +++++
-
- Now what you really want to know: The type of shaft a person should use
- is one of the most often asked questions. It is also one of the most
- unanswered questions. Choosing the material, flex, and kickpoint of a
- shaft will depend entirely on what "feels" right when you swing the
- club. Someone with a high swing speed may choose a steel shaft with a
- flex rating of X and a low kickpoint, while someone with the same swing
- speed may choose a graphite shaft with a flex rating of R and a high
- kickpoint. The general consensus is see your local Pro and see what
- he/she recommends. Make your decision from there. For more information
- please refer to Dave Tutelman's "Designing golf clubs" articles.

- Types of Grips
- ==============
-
- Rubber
- +++++++
-
- Rubber grips are made by adding granulated cork, as well as other
- materials in the liquid rubber. The "cork" serves to displace the
- rubber, and is the reason many grips are called "composition" grips. It
- also makes the overall weight of the grip lighter. The rubber/cork
- blend is checked to assure the proper viscosity, and is then molded in
- a high pressure molding machine. After molding, the grips are sanded
- and painted. Some of the features of rubber grips are: easy
- installation, "reminder ribs" for hand placement, and they are less
- expensive.
-
- Leather
- +++++++
-
- Most of the "stars" over forty use leather, while the younger players
- use various rubber molded grips. The reason has very little to do with
- the quality or playability of the grip, but simply a difference in what
- each generation has been accustomed to. One of the features of leather
- grips (generally made of cowhide or calfskin) is that they have a nice
- soft, pliable, tacky feel. A few of the drawbacks are its difficulty to
- install, and its price.
-
- Cord/Half-Cord
- ++++++++++++++
-
- Most of the more popular rubber models come in an optional "cord" grip,
- in which strands of fabric thread are embedded in the rubber grip. This
- makes for a better non-slip contact with hand or glove, especially when
- wet with rain or sweat. However, it does wear out gloves faster than
- non-cord grips. (Hands, too. :-)
-
- Many of the "cord" models also come as "half-cord", in which the top of
- the grip (where your thumbs are) are smooth rubber and the bottom
- (where your fingers wrap around the club) are cord.
-
- Quick Comparison
- ++++++++++++++++
-
- ** Rubber Grips **
- o Slip-on design
- o Easy to install
- o Less expensive
- o Rough when corded
- ** Leather Grips **
- o Usually wrapped spiral design
- o Harder to install
- o More expensive
- o Natural soft, tacky feel
-
- Oversized/Undersized
- ++++++++++++++++++++
-
- Grips come in a standard size, but can be padded to a larger diameter
- with tape on the shaft under the grip. It is also possible to get
- larger and smaller diameter grips. A few of the pros and cons:
-
- ** Oversized **
- o For larger hands
- o Minimize arthritis pain
- o Decreases hand action, promoting a slice
- ** Undersized **
- o For smaller hands (most women)
- o Increases hand action, promoting a hook
-
- Notes
- +++++
-
- Now what you really want to know: The type of grips a person uses will
- be based on "feel". Some people like the natural soft feel of the
- leather grips, while others refuse to use anything but corded composite
- grips. Try going to a local golf shop and seeing which grips "feel"
- right - and you can afford.

-
-
- Scoring/Handicapping Systems
- ============================
-
- All of the following information was taken from articles posted to
- rec.sport.golf with permission from the authors.
-
- ** Handicapping Systems **
- ==========================
-
- Quick Reference Allowance (QRA)
- +++++++++++++++++++++++++++++++
-
- The USGA has developed a simple, but relatively effective estimator of
- a player's ability called "QRA" for "Quick Reference Allowance." QRA is
- not a substitute for the USGA Handicap System, but can produce fairly
- equitable results and is the best system for handicapping the otherwise
- "un-handicapped."
-
- To create a player's QRA, the tournament committee simply asks each
- un-handicapped player to submit his three best scores made on a
- regulation course (with par of 68 or more) in the last 12 months.
- Combine these scores with any previous scores that the player has made
- in a tournament in the past two years.
-
- The player's QRA is the second best score minus 70 for men or 73 for
- women.
-
- Modified Peoria System
- ++++++++++++++++++++++
-
- The next best alternative, according to USGA studies, is to use a hole
- score selection system, often called the "Peoria system." Under this
- system, a player learns his handicap after the round is completed. By
- this method, the committee secretly selects a par-3 hole, a par-5 hole
- and four par-4 holes from an 18-hole course. The par-4s should be
- representative in length and difficulty with two chosen from the front
- nine and two from the back nine.
-
- A modified Peoria handicap is calculated by adding the player's strokes
- over par on the six selected holes, and multiplying by 2.8. This will
- equal the player's allowance to be deducted from his gross score. The
- maximum hole score for allowance purposes is three over par on par-3s
- and 4s and four over par on par-5s.
-
- Callaway System
- +++++++++++++++
-
- The Callaway System is a so-called "one-round" system or "worst-holes"
- system that compresses the spread of gross scores when converted to net
- scores. It is not a reliable handicap system and produces a result such
- that the player with the lowest gross score almost always becomes the
- low net score winner. Most players with higher gross scores are given
- net scores within a few strokes of the winner so that most players can
- feel competitive.
-
- By the Callaway System, a player's allowance is determined after each
- round by deducting from his gross score for 18 holes the scores of the
- worst individual holes during the first 16 holes. The table below shows
- the number of "worst hole" scores he may deduct and the adjustment to
- be made, based on his gross score.
-
- Scheid System
- +++++++++++++
-
- The Scheid System is an alternative "worst-score" system, that has two
- advantages over the Callaway method:
-
- 1. It allows for a wider range of scores (up to 151)
- 2. It gives players who normally cannot compete for low gross score an
- opportunity to win.
-
- Notes
- +++++
-
- Please refer to the article on "Handicap Systems" for more information
- and the tables.
-
- ** Scoring Systems **
- =====================
-
- Stroke Play
- +++++++++++
-
- (also called Medal Play)
-
- Low gross -- no adjustment for handicap
-
- Low net -- subtract your handicap, low score wins
-
- Match Play
- ++++++++++
-
- Two players play head to head. Total strokes are not important. The
- winner is based on who wins the most holes. The match is over when one
- player is ahead by more holes than the number of holes remaining.
-
- Stableford
- ++++++++++
-
- Points are allocated based on the net score of each hole. Handicaps are
- allocated based on the index of each hole.
-
- You deduct the allocated handicap per hole from the score on the hole
- and the points are allocated against the equivalent net score for the
- hole.
-
- The exact points which are allocated seem to vary.
-
- Best-Ball
- +++++++++
-
- This refers to a team event which may comprise 2, 3 or 4 players. Each
- player will have his/her stroke allowance and the lowest net score
- would be recorded at each hole. The total for the complete round would
- be the teams best-ball score.
-
- Scramble
- ++++++++
-
- Normally a team of 4. Each player tees off at each hole and then the
- team selects the ball which is in the best position and ALL play from
- that spot. This repeats for all shots until the hole is finished.
-
- Foursomes
- +++++++++
-
- This is where 2 players play one ball hitting alternative shots. One
- player will tee off at all the odd numbered holes and the other at the
- even numbered holes, no matter who was the last player to play on the
- previous hole.
-
- Par
- +++
-
- Similar to stableford as far as the allocated shots are concerned but
- you either win, halve or lose the hole (+ 0 -). Its a little tougher,
- as anything worse than a net par is a loss. At the end you add up your
- wins against your losses.
-
- Chapman
- +++++++
-
- (2 man teams)
-
- Each player hits a tee shot. They then each play a second shot using
- their partner's ball. At this point, they select the best ball and the
- player who did not hit it plays, alternating shots until the ball is
- holed (only the first two shots are hit by both players).
-
- Pinehurst
- +++++++++
-
- (2 man teams)
-
- Pinehurst is similar to the Chapman format, except that each player
- hits a drive, and the best drive is then chosen and players alternate
- in from there.Unlike the Chapman, players do not BOTH hit second shots
- from their partners drives.
-
- Hero-Bum
- ++++++++
-
- (4 man teams)
-
- The best and worst scores are counted (net or gross).
-

-
- Handicap Information
- ====================
-
- Getting an "Official" Handicap
- ++++++++++++++++++++++++++++++
-
- There are a few ways of getting an "official" handicap. The easiest way
- is to become a member of a local course. Although this can sometimes be
- expensive ($100 and up), it does entitle you to a few extra benefits -
- such as reduced green fees, preferred starting times, as well as an
- chance to play in club sponsored tournaments and meet new people.
-
- Another way to get an "official" handicap is to join a local golf
- "association". For a small fee (+/- $40) they will establish a handicap
- for you. Depending on the association, you may also get reduced fees at
- certain clubs, as well as being able to play in association sponsored
- tournaments and meet new people.
-
- Calculating a Handicap Index
- ++++++++++++++++++++++++++++
-
- It is possible to calculate your own handicap index, although it may
- not be accepted for use in tournaments. None the less you can calculate
- your index and use it to keep track of your progress, and/or use it
- when playing with other people.
-
- The USGA Handicap Index is usually based on the best 10 of your last 20
- valid 18-hole rounds, but can be computed from fewer rounds. For each
- round, you will need to know both the USGA Course Rating and Slope.
-
- The usual first step is to compute your "Adjusted Gross Score"
- according to the "Equitable Stroke Control" (ESC) procedures. To
- calculate the Adjusted Gross Score, you first calculate the Course
- Handicap based on the slope of the course you are playing using your
- index. This will determine the maximum score for each hole (ESC). If
- you haven't yet established a handicap index, then you are to start
- with the base index which is 36.4 for men and 40.4 for women. From your
- Adjusted Gross Score you compute the "Stroke Differential" for that
- round according to the following formula:
-
- (AGS - Rating) x 113
- Differential = ------------------------
- Slope
-
- You should *ROUND* the Differential to the closest tenth (one place
- after the decimal point).
-
- Ideally, you'll have your last 20 Differentials, of which you take the
- lowest 10, average them, multiply the result by 0.96 (96%), and *DROP*
- (not round) any digits after the tenths digit.
-
- Equitable Stroke Control
- ++++++++++++++++++++++++
-
- For handicap index purposes *ONLY*, there are limits to the maximum
- number of strokes you are allowed to take on any given hole. If you
- take more than that, the score you use to compute the Stroke
- Differential for that round must be adjusted downward by the number of
- strokes you exceeded the limit. These limits are based on your Course
- Handicap (not your Handicap Index). The ESC procedure was changed early
- this year to a simpler method. All you need to do is remember this
- simple table:
-
- Course Maximum Strokes
- Handicap Allowed per Hole
-
- 9 or Less 6
- 10 - 19 7
- 20 - 29 8
- 30 - 39 9
- 40 - 49 10
- 50 or more 11
-
- For more information regarding calculating and using your Handicap
- Index, see the files regarding calculating your handicap.

-
- What is a push/pull fade/draw hook/slice
- ========================================
-
- Push
- ++++
-
- A ball whose flight path is straight, with negligible sidespin, that
- ends up right of the target. The incidence angle of the clubface is x
- degrees to the right of the target , and where the PATH of the clubface
- is also x degrees to the right of the target (inside to outside path).
-
- Pull
- ++++
-
- The opposite of push: A ball whose flight path is straight that ends up
- left of the target. The incidence angle of the clubface is x degrees to
- the left of the target, and where the PATH of the clubface is also x
- degrees to the left of the target (outside to inside path).
-
- Fade
- ++++
-
- A straight shot with a minimum of sidespin, such that there is slight
- but noticible left to right travel by the ball at the end of its
- flight. The key words are slight sidespin. Since the forward energy
- force must be much greater than that of the sidespin, such that as the
- ball slows down at the end of its flight, using up the forward
- direction energy, the sidespin takes over and gives the ball its left
- to right 'fading action'. The club face is generally open a few degrees
- at impact, but the club path is straight along the intended path
- (directly at the target).
-
- Slice
- +++++
-
- A curving shot from left to right whereby severe sidespin has been
- imparted to the ball such that this spin is of a great enough rate to
- govern its direction in a more Left to Right mode than straight. The
- club path is outside to inside with a clubface usually open many
- degrees.
-
- Draw
- ++++
-
- The opposite type of shot than a fade. A straight shot with a minimum
- of sidespin, such that there is slight but noticible right to left
- travel by the golf ball. at the end of its flight. The key phrase is
- slight sidespin. Since the forward energy force must be much greater
- than that of the sidespin, such that as the ball slows down at the end
- of its flight, using up the forward direction energy, the sidespin
- takes over and gives the ball its right to left 'drawing action'. The
- club face is generally closed a few degrees at impact, but the club
- path is straight along the intended path (directly at the target).
-
- Hook
- ++++
-
- The opposite of a slice. The path is usually inside to outside with a
- club face closed more than a few degrees.
-
- Hope this helps. For more info, see: "The Search For The Perfect Swing"
- by Alistair Cochran and John Stobbs.
-
-
-
- What causes / How do I cure a slice/hook
- ========================================
-
- What causes it
- ++++++++++++++
-
- For the most part, a hook or a slice is caused by the clubface being
- opened or closed upon contact. Most people also tend to agree that an
- inside-to-out swing plane causes a hook, and an outside-to-in swing
- plane causes a slice.
-
- o = ball x = clubhead path
-

- x
-
- HOOK STRAIGHT SLICE
- ---- -------- -----
-
- How do I cure it
- ++++++++++++++++
-
- Generally to fix a hook or a slice, you will want to change the path
- which your clubhead follows before striking the ball. If you are having
- a problem with a hook/slice, try to ensure that your clubhead has a
- straighter swing path.
-
- If after trying to change your swing path, you see no improvements, go
- see your local Golf Professional.
-
-
-
- What clubs should I buy
- =======================
-
- Well, you could start by sitting down and reading through this
- document. By honestly judging your abilities, you may be able to decide
- if you need peripherally weighted or muscleback clubs.
-
- The next logical step is deciding on how much money you want to or are
- willing to spend for new clubs. Keep this number in mind when your
- shopping for new clubs, if you don't you could wind up spending much
- more than you planned on.
-
- Once you have an idea of what type of clubs you want and how much you
- plan on spending, go down to your local golf shop or club and try to
- hit a few clubs. If your allowed, try to play a round or two with demo
- sets. By actually using the clubs in a "golf round" situation, you may
- be able to decide if the clubs look, feel, and play the way you would
- like them to. If you feel uncomfortable with the clubs don't buy them -
- just because your golfing buddy swears by XYZ, doesn't mean you should
- too.
-
- If after doing the above, you still can't decide for yourself, go see a
- local professional or clubmaker and ask for some help. Either should be
- more than willing to help you make a well informed decision.
-
-
-
- How do I build my own clubs
- ===========================
-
- Start off by ordering some catalogs from some of the component vendors
- (an annotated list is available in the archives). While you are waiting
- for the catalogs to arrive, get some of the articles regarding club
- design and assembly which are available in the archives.
-
- Let us know how your clubs turn out!
-
-
-
- USGA Course Rating Information
- ==============================
-
- The following information is a brief explanation. For more information
- please refer to the "Slope Information" article by Randy Schrickel.
-
- YARDAGE Rating
- ++++++++++++++
-
- "Yardage Rating" is the evaluation of the playing difficulty based on
- yardage only. It is the score a scratch player on his game is expected
- to make when playing a course of average difficulty.
-
- USGA COURSE Rating
- ++++++++++++++++++
-
- "Course Rating" is the evaluation of the playing difficulty of a course
- for scratch players. Course Rating is expressed in strokes and decimal
- fractions of a stroke, and is based on yardage and other obstacles to
- the extent that they affect the scoring ability of a scratch player.
-
- Courses are rated by authorized golf associations, not by individual
- clubs.
-
- USGA SLOPE Rating
- +++++++++++++++++
-
- "Slope Rating" reflects the relative playing difficulty of a course for
- players with handicaps above scratch, whereas Course Rating is based
- solely on difficulty for the scratch player. The lowest Slope Rating is
- 55 and the highest is 155. The average Slope Rating for men and women
- is 113.
-
-
-
- Etiquette Tips
- ==============
-
- ** Proper Etiquette **
- ++++++++++++++++++++++
-
- o Do not leave your ball in the hole when you make a putt/chip.
- Golfers are a superstitious lot and many think that their ball
- will not fit in the hole if there is already another one in
- there.
-
- o If you putt/chip your ball near the hole and do not plan to
- putt out, mark your ball with a coin or ball-marker. Aside from
- being a distraction, other players will incur a 2 stroke
- penalty if they play a putt from the green and their ball hits
- yours.
-
- o As much as it may interest you, do not stand directly behind
- another player's intended target line. This is a violation of
- the rules if the player is your partner and otherwise
- distracting because the player can usually see you out of the
- corner of his/her eye.
-
- o When playing for the first time with someone, be conservative
- at first about complimenting or critiquing a shot. Follow the
- lead of his friends, pay attention to his comments, and wait
- until you have a good understanding of what is a good and bad
- shot for a particular player. Don't assume that everyone's
- standards are the same as yours.
-
- o Invite faster groups to play through.
-
- ** Slow Play **
- +++++++++++++++
-
- o Be ready to play when it is your turn. Proceed to your ball as
- soon as it is safe and begin preparing for your shot. On the
- green, survey the contours and grain while other players are
- putting if you can do so without being distracting.
-
- o Write your scores on the scorecard when you reach the next
- tee.
-
- o When playing from a cart, drop one player off at his/her ball
- with several clubs and, if it is safe, drive the cart to the
- second players ball. This way, the two players sharing the cart
- can both prepare for their shots at the same time.
-
- o If you take a cart and you are not allowed to leave the cart
- path, drive the cart until it is roughly even with your ball
- and take several clubs (maybe the one you think you will need
- and one above and one below) with you to your ball. If you
- really have no idea what club you will need, pull your bag off
- the cart and take the whole thing with you to your ball.
-
- ** MOST IMPORTANT **
- ++++++++++++++++++++
-
-
- o If attending a pro tournament, never say "You're the man!"
- after a drive. If you do, and are publicly identified as such,
- your rec.sport.golf privileges will be revoked for a period of
- not less than 2 years per incident.
-
-
-
- Hitting in Regulation
- =====================
-
- Fairways
- ++++++++
-
- Hitting a fairway is exactly that, your ball comes to rest off the tee
- (except par 3's) in the fairway cut of grass.
-
- Greens
- ++++++
-
- Hitting a green in regulation means that your ball will be on the
- putting surface in 1 shot on a par 3, 2 shots (or less) on a par 4 and
- 3 shots (or less) on a par 5.Just subtracting 2 putts from the par
- gives you the "Regulation" number of strokes to reach the green.
-
-
-
- USGA Information
- ================
-
- Joining the USGA costs $25 per year. You get a current rule book, nine
- issues of Golf Journal, with special issues for the US and Senior Open,
- as well as their catalog of golf goodies and a bag tag.
-
- The money helps support the USGA which sponsors 14 various amateur
- tournaments, administers the rules of golf, conducts equipment tests,
- does turf research and much more.
