My tip trimming fiasco had the benefit of raising an interesting question.
I have known for a long time that steel cpms don't equate to graphite cpms. As a result, I've basically ignored them. Also, nearly every graphite shaft I've used has been in a driver, with no tip trim. However, once I posted the cpms I got from the PF shaft, several very experienced clubmakers said "that's too stiff." The question is "How close, in a VERY general sense, are steel cpms to graphite cpms?" They obviously must be close enough to make some basic approximations. Thx, /Ed
