of course.I was talking about the '90s, when there was a reference of 5.5s
to R, etc...what we do/speak about today as clubbuilder/fitters and what we do
in general discussion are different..I have many clients who think all Rs
are Rs, Ss all the same S etc. It's a study in education. I
Personally I am surprised to see any professional builder using terms like "R"
or "S". I though to fit some one correctly you find a shaft and head combo
that gives you the desired ball flight and then figure out what frequency to
cut them too to hit them fairly straight. The terms "R" or "S"
Scott...I believe some of the AGCP members use the PCS flex designations and
some use Dana Upshaw's 5i or 6i charts. I generally ream .355" to .370" with
the customer's agreement. From what I've seen, using taper tips sometimes
results in a slope of 6 cpm...and at his swing speeds, 'feel' is
back in the 90s, I believe Rifle 'R's were 5.5s. I played them and they were
like a pipe because my 5i ss was in the 78mph range. Later, I beieve Rifle
adjusted the 'R' to 4.5, I believe. PCS made up a chart [ maybe Dave Eagar
created it ]that compared PCS's slope vs Rifle 4.3 slope. The maj
I have spoken in the past to Kim about why he designed the rifle with a 2 1/2
inch clamp. The rifles is meassured for stiffness from the butt. The butt is
where you will hold the club so that's where he designed it from. A blank
rifle shaft has a uniflex reinforced tip. It plays stiiffer bec
You know with that swing speed the kid would be better off with a set of
Project X's instead of regular rifles. He is going to possibly get some
ballooning with regular or flighted rifles. I do mean a real set of project
X's not the junk Callaway is trying to pass off as Project X's nowadays.
This just occurred to me (us old farts have to wait for inspiration) Why not
clamp the Rifle shaft at 2 1/2", record the freq, then clamp at 5" and compare
the difference. As I recall, Rifles were clamped at 2 1/2" with a really heavy
tip weight attached. Virtually all their shafts freq'd and p
yes, these were tapers. I really hate using taper tips, but I didn't have a
choice in this case. I've noticed the same thing that Robert pointed out in
that when I measure 5.0 and 5.5 shafts, they seem to fall in ranges that I
expect. But starting at about 6.0 and up, they seem to really jump
Scott...you using taper tips unless you reamed them outthe butt cpms might
or might not jump depending on what length shaft you were provided..
