In experimenting with light head weight clubs I run
across the old question of whether frequency or shaft deflection is the best
indicator of the proper "flex" for a given persons club set. Also torque may
modify the choice.
For the past several years I've used a driver with a
65 gram P1230 Quadrax shaft, a 200 gram head, combined into a 46" club with a
frequency of 230 cpm. I've now switched to the light driver mentioned below and
after several weeks still like it better than any I've tried. Played in our
senior tournament and drove the ball very well all day. I'm in the 70+ class,
which has by far the most contenders, and played with a player from each of
the lower age classes and stayed with them in the driving area.
However didn't putt well so came in 4th place.
My current light driver is a 46 gram R flex
PowerLite shaft, a 176 gram head, combined into a 46" driver with a frequency of
247 cpm. I've tried all the available PowerLite flexes, S, R, A, L and find the
R flex giving the best results to date.
I'm beginning to lean toward shaft deflection as
being a better fitting indicator than is frequency. Would like comments on
others findings in this area. BTW, I've made tests to verify the form of the
equation for frequency of a golf club given on page 230 in "The search for the
perfect swing". The equation includes a factor of 0.24 times the club mass for
modifying the frequency of the final club. This isn't really a constant but
varies with shaft materials and bending profiles, but it does show what
happens.

Today I'll try a new 180 gram head with a 55 mm tall
face on a stiff flex PowerLite shaft at 256 cpm. I tried it on the A flex
shaft and didn't hit it very well. Also am trying a "Double Hump" putter.
Works well on the living room floor but then most putters do. It certainly isn't
a copy of the two ball. It weighs 400 grams and is face balanced using a
straight shaft! It doesn't have the big mass between the rear of the sole
plate and the rear of long top of the head. I think the MOI of the REAL 2 Ball
would be much greater. But then so is the price!
