Matching Golf Shafts
To Your Students

Matching
a golf shaft to a student can be, at times, truly a challenge. There
are several key elements in selecting the proper shaft. The teacher
and player must work as a team to make certain the feel and performance
of the shaft best matches the playability and feel requirements
of the player.
Shaft
fitting is an investigative process; the more knowledge that can
be discovered about a golfer’s swing, the better the fit is likely
to be. As the player’s teacher, you have a unique insight into this
fitting parameter. A look at the playability and performance of
the player’s current clubs is a good baseline from which to work
when fitting shafts to that player.
Shaft
fitting is often termed a “risk-reward” proposition. The key is
to find a shaft that the player is able to swing under control,
yet one that produces maximum distance. Generally, a softer shaft
will produce longer shots, but with less control. A longer length
or lighter weight shaft often does the same thing. Stiffer, shorter
and heavier shafts often improve accuracy, but at a distance cost.
The
teacher must keep a number of things in mind as he or she guides
a player through a shaft fitting session. How flexible can the shaft
be before the golfer loses control? How stiff before the player
starts over-swinging? When considering shaft weight, how light of
a shaft can the player use without losing control? How heavy can
the shaft be before the swing slows, the player fatigues, or the
club feels too heavy? Concerning length, how long can the club be
made before control is lost or the club feels too heavy? How short
might the club be until distance or feel is compromised?
Another
factor to consider is the weight distribution of the shaft. If a
high percentage of weight is toward the tip of the shaft, the resulting
club will feel heavier and ball flight will be higher. If the balance
point is high, the feel will be lighter and ball flight lower. Bend
point or flex distribution is also a factor. Bend point has little
effect on actual ball flight, but does have a noticeable effect
on club feel. Lower bend point shafts will feel softer and will
create a club with more head feel. Higher bend shafts will feel
stiffer and will tend to have less head feel.
A
player’s tempo can be used to fine-tune the shaft to your student.
The faster a golfer swings, the better chance he or she will be
able to more effectively control a stiffer shaft. A good example
of a faster-paced swing is the one belonging to Tom Watson. He has
played higher frequency clubs throughout his career. More flexible
shafts are better suited to slower-paced “Fred Couples-type” swingers
of the club.
A
faster swinging player using softer shafts will add distance to
his shots, but will quickly lose control. The converse applies;
a player with a slow swing tempo using stiff shafts may gain a measure
of control, but will almost always lose distance and feel, something
a slow swinging player typically cannot afford to do.
The length of a player’s backswing should also be factored in when
choosing a shaft. The longer and smoother a player’s swing, the
more flexible the shaft selection for that player. Players with
very fast swings – Lanny Wadkins comes to mind – will be better
matched to a stiffer shaft.
Swing plane may have an effect on shaft selection as well. A player
with an upright swing plane will tend to hit higher-than-average
shots as a result of the longer arc of such a swing type. If that
player uses softer shafts, ball flight will be higher yet. If the
upright-swinging player desires to lower ball flight, a stiffer
tip shaft may provide such flight. For golfers with flat swing planes
who most often have lower trajectory shots, stiffer shafts may be
difficult to hit very high, making approach shots to the green very
hard to hold. Softer shafts may help “kick” the ball into the air
higher, helping to achieve an acceptable trajectory.
Shaft
length selection is a direct result of how the player swings the
club. Player height, arm length, posture and hand position at impact
and address combine to influence length selection. Not all tall
players need long clubs, and not all shorter players need short
clubs. Hall-of-Famer Gary Player stands 5’7” tall, yet used a steel-shafted
44-45” driver throughout most of his career.
As a general rule, longer clubs will provide more distance potential
due to the longer swing arc they create. But, as usual, there is
a trade-off. Longer clubs may be harder to control as they are more
difficult to return squarely to impact. Typically, longer clubs
are heavier as well, perhaps making fatigue and/or player strength
a factor. The key element when examining shaft length is to choose
the longest length club that a player is able to swing under control,
leading to consistency and longer shots.
The
aforementioned factors combine to produce shaft performance. Today’s
shaft fitting is primarily determined by either swing speed or launch
angle, or both. It is generally assumed – sometimes incorrectly
– that a player who swings the club at a higher speed is best fitted
with a stiffer shaft and the slower-swinging lady, junior or senior
will be better matched with a softer shaft.
Swing
speed does seem to be a possible starting point in shaft selection.
Nearly all manufacturers list their shafts according to certain
swing speed ranges. As an example, True Temper’s EI-70 graphite
shaft, a popular shaft among better players, has a speed rating
of approximately 90 miles per hour for the “R” shaft version and
96 for the “S.” Does this mean that any player who swings at 90
mph should use the EI-70? Certainly not. The shaft is a moderately
heavy shaft with a lower torque than most shafts on the market.
This shaft is designed for a stronger, faster-swinging player. The
player who has a long, slow swing will tend to hit this shaft shorter
and with less control than will a stronger player, even if they
both achieve a swing speed of 90 miles per hour.
Enter
launch angle as a factor in fitting shafts, as well as balls. By
measuring launch angle and ball speed using a specialized machine,
the teacher can determine the best shaft/ball combination for the
player. Indeed, at this point fitting involves finding the proper
shaft, club loft and golf ball. Ball speed equals distance. Spin
rate is a direct result of ball speed and club loft at impact. The
basic concept of launch-angle driver fitting is to provide the player
with a club/ball combination that produces the highest ball speed
and longest carry (highest loft) with the least amount of spin.
The goal of launch monitor shaft fitting is to find the combination
that produces the highest launch, flattest trajectory and lowest
ball spin. This will result in the greatest distance potential for
your student.
Shaft
selection is a multi-step process that involves a number of shaft
parameters. Every shaft will have its own unique specifications,
yielding overall performance and playability characteristics. The
same applies to balls when fitting with a launch monitor. What plays
well for one student is often a poor choice for another.
Utilizing
knowledge about shafts and their specifications related to playability
will help the teacher and player work toward the selection of the
proper shaft. The shaft is truly a key element of club performance;
choosing the correct shaft for a player’s swing can immediately
improve direction, trajectory, feel and distance. Individual players
have their own unique playing characteristics; so do golf shafts
and balls. Matching them will lead to improved performance and lower
scores just about every time.
