I will post a video of shafts under flex load in a roller bearing spine finder, that also reads the flex while the shaft is loaded. You will be amazed at the flex change simply by rotating the shaft.
IMO: Once you see this you will know its a BIG DEAL. Some shafts have very dominant spines, some not so much. generally 3-4 iron shafts out of 8 will have dominant spines. That is why you have some irons in your bag that are your friends, and some you don't get along with, and perhaps some that are lasers as the spine was 'randomly' set to a orientation that plays well.
It would kill OEM profits to cpm, sort, spine, Flo shafts for install, so they deny there is a factor in the first place.
So getting a shaft "Pured" should make a difference.
