DIfference's between KBS Max 90 S and Project X LZ 6.5
Looking for input on these two shafts. I've been playing with a set of Callaway GBB CF 19 irons with KBS Max 90 Stiff shafts and just picked up a set of Callaway Apex irons with Project X LZ 6.5 shafts. Wonder what the major differences are going to be between the two? I know the PX shafts are heavier and have a lower trajectory listed. I hit the new Apex well, although slightly lower. I'm not used to them yet and before I made any changes I'm wondering if the lighter Apex heads will offset the difference of the heavier shafts or if I should swap them out with each other to keep a consistent flight to not affect my game? I'm afraid of spending too much time playing with the new setup and it changing my swing so trying to make a call on what direction to go in. If I do swap shafts what am I looking at spending to do so at a pro shop and is it a bad idea to make that kind of change?
