It's a safe bet that if you're an avid golfer, you've
bought quite a few drivers in your life. It's also a
good guess that you've got some drivers that "didn't
work out" in a closet or the garage. It's amazing
that golfers are so tolerant about losing money on golf
equipment. They go into a golf shop, waggle a driver
a few times, maybe hit some practice shots into a net,
and lay out several hundred dollars without ever taking
the club to the course. Fact is, most new drivers never
make it "in the bag".
There is a way to raise the odds that the next driver
you buy will be one you will actually play with. The
purpose of this article is to lay out six steps that
will help you make sure that the next driver you buy
fits your game and doesn't end up in the closet or for
sale on eBay.
- Knowing your swingspeed with your driver is the
first step that will get you in the ballpark. There
are many ways to get this done. Most golf shops have
computerized fitting equipment that measures swing
speed as well as other statistics. Swing speed is
measured in miles per hour. As a rule of thumb, 100
MPH is the "macho" line. A swing speed under
90 will require a flexible shaft. Most golfers are
in the 90-100 range. 100 to 110 is the strong amateur
and average professional range. Gorilla territory
starts about 110. Tiger and the long drive contestants
are north of 120.
- Understand "frequency matching". In the
old days, golf clubs came in A, R, S, and X flexes.
Today, a much more sophisticated method of measuring
"stiffness" has been developed. The golf
club is clamped at the grip an oscillated. The oscillations
are measured by an electronic instrument in "cycles
per minute" or CPM. The faster the club oscillates,
the stiffer the shaft. The measurements for each club
are plotted on a "slope chart". (Illustration)
The slope chart divides each flex (A, R, S and X)
into ten sub flexes. According to Royal Precision,
the makers of Rifle shafts and the inventors of frequency
matching, 4.5 is equivalent to an "R", 5.5
is an "S" and 6.5 is an "X". Consequently,
a 6.0 would be midway between an "S" and
an "X". In matching swing speed to flex,
it is perfectly reasonable to say that you want a
"driver on a 6.0 slope" that measures 253
CPM at 45". You know exactly what you're getting.
- Get some professional advice and recommendations.
The artistic part of fitting a driver goes beyond
matching a swing speed to a certain flex. The way
you swing will determine your best final frequency
choice. If you swing hard and "load" the
shaft, a club fitter will recommend a shaft at the
high end of the appropriate CPM range. Conversely,
if you are a smooth swinger with a "soft transition"
you will probably get better performance from a shaft
in the lower end of the appropriate range. An experienced
club fitter will also be able to recommend specific
shafts with performance characteristics to deliver
a higher or lower trajectory. Your club fitter should
have some test clubs to try out.
- Base your choice on measurable data. It's possible
to get started fitting a driver indoors, hitting into
a net. However, there is no substitute for hitting
balls and watching the ball flight. This can only
be done outdoors, at a range. Insist that your club
fitter allow you to take a few recommended test clubs
to an outdoor range. Ideally, your fitter would accompany
you and he would have access to electronic equipment
that will help compare the performance of your test
clubs. We use the Distance Caddy which is also built
into the Callaway fitting system. The Distance Caddy
gives the carry distance, head speed, ball speed and
delivers an "efficiency" rating. The efficiency
tells you how well the head transfers energy to the
ball, a shorthand calculation for how "solid"
the shot is. When you think about it, how else are
you going to know which test club performs the best?
You can't see where the balls are landing. Basing
a choice on "feel" alone is unreliable.
- Make sure what you buy is what you get. If you
buy a driver from any of the major manufacturers,
be sure to check the frequency before you accept delivery.
It is very common for name brand drivers to be different
from what you expect. For example, Titleist drivers
have a 5 inch "throughbore". The effect
is that shafts play much stiffer than specified. If
you buy a "Graffaloy Prolite S" in a Titleist
975 it will probably play to an "X". Also,
certain shafts are much stiffer than the designated
flex. For example, Proforce 75 "S" flex
plays to the frequency of an "X" in most
drivers, especially Titleist. Proforce 65's, on the
other hand, tend to play true to flex. Once again,
the knowledge and advice of an experienced club fitter
can be invaluable in making sure that you actually
get the driver that fits.
- Finally, have patience and be willing to experiment.
Sometimes, Americans are accused of wanting a "quick
fix". The only way to understand the right driver
for you is to try a lot of different drivers. But
testing is only effective if you know what you are
testing. For this reason, it is imperative to work
with a club fitter who can tell you precisely what
he is recommending and then allow you to hit test
clubs that have been measured and calibrated. Make
sure that you get some reliable performance data from
electronic equipment like a Distance Caddy. Then,
you will have the information and experience you need
to make an informed choice.
In the end, the goal is to make sure that you find
a driver that fits your swing. A good fit comes from
a combination of factors. Match swing speed to flex,
adjusted for your individual swing characteristics.
Experiment with several different drivers with known
specifications under the watchful eye of an experienced
PGA pro or club fitter. Finally have the patience to
try recommendations with an open mind. The "Magic
Driver" is frequently an unlikely choice that "just
works". |
