Hi All,
Recently a club fitter came to my club and set up shop on the driving
range for 5 days to fit golfers and build/retrofit clubs with a
zero frequency slope. He either built you a new set of clubs with
their heads or re-shafted your clubs with their shafts trimmed to the
zero slope. He also spine aligned and swingweight matched the
clubs. The theory on this is that every club will unload
at the same point at the bottom of the swing. He calls
it Single Flex Matching (TM). He maintains that it would be
cost prohibitive for club manufacturers to achieve
this. He measured my 3,5,7,and 9 irons and the frequency
numbers were 301, 310, 317, and 325. They are Rifle lite 6.0 shafts
and he felt way too stiff for me. He watched me hit some balls and
recommended that I use 298 cpm (steel shafted) irons and 243 cpm
(graphite shafted) woods. I am a zero handicap (6'3" 40 year old)
with a smooth (slow to medium tempo) swing with a 5 iron swing speed of
about 90 mph. What are your thoughts and feelings about this method
and what frequency slope do most of you use when building custom
clubs?
