I'm currently playing every day, and my swing speed keeps increasing therefore my 50g stiff shaft for my driver isnt cutting it anymore. I find that on contact the shaft feels too whippy (for lack of better words). I cant get a consistant ball flight with it because of how much the shaft flexes, I'm trying to figure out what kind of shaft to get but I dont kow what would be best for me, any tips would be much appreciated.
