I have A flex shafts and I want to make them play closer to an R flex. I will only be using the shafts on my 6i-pw so a total of 5 shafts. I have the complete set of A flex 3-PW. My question is if I take the shafts from 5-9 which would be 1/2" longer than the 6-pw and then cut 1/2" off the tip of these would this be enough to stiffen the shaft enough to lay like an R or am I better to trim 1" from the butt of the shafts from the 4-8i shafts?

The shafts are the frequency matched Mercury Pro Kevlar are a 75g shaft with 3.3 torque

Thanks, Luc
