Recently purchased a Precision 2 v4 combo flex (R/S) graphite iron shaft from Golfworks and I am looking for the trim codes. I intend to install this shaft in a 7 iron
Talked to the Canada guys and the trim codes for this shaft would be IR7 / IR10 for the combination flex. IR7 for the weaker flex and IR10 for the stiffer flex. Below is a link to our trim charts. You will need to scroll down to the second page to find the IR7 and IR10 trimming instructions.
