What flex shaft should i get for my driver?
Here’s what I learned from my instructor and having checked this myself, I know it to be true. The “flex” marking on any manufacturer’s graphite shafts mean nothing. There is a wide range of “actual” flex in each “category” (X, S, R, A) and no two shafts marked “S” will flex the same even in the exact same brand and model driver. Same with all flexes. What you need to do is demo a bunch of drivers (it doesn’t matter what brand, or model) with a range of R and S flexes. Find one that works for you (gives you the feel, trajectory and ball flight) you like and ask the salesperson to test it for actual flex. That number will be in Cycles Per Minute, or CPM. Knowing what your ideal CPM number is, you can then pick the exact driver you want and have them find one that matches YOUR ideal CPM number + or – two to three CPM’S. THAT’S the “flex” you need. Not the designation on the shaft, but your ideal CPM number.
