what is AoA and Moi really do?
sorry if this may be off topic but I have to ask.
last year I used a xhot 10.5. it got the ball in the air for me very well, but I hit it towards the heel a lot.
this year I went to my pro because the xhot was just to high in flight and there was no roll, so we worked on my swing and shafts. even with a better swing heel shots would creep back into my game. we worked on numbers at this point, and changed shafts by the time we got to a shaft that got my numbers decent and a lot more center of face, I noticed there was a i25 sitting in his shop, so I asked him I I could take it for a spin.
at this point we turned on the machine and looked at the numbers.
my xhot still not very center hits was spinning in the 3000 range and up.
when I hit the i25 I almost fell over from the feel. center top hit spin rate 2500 ish.
I was able to to stay in the 2000 range and hit more center to toe with the i25. I wish I remember my other numbers but all I rember is spin and distance.
what in these 2 clubs would make me hit one better then the other?
Angle of attack, when positive for a driver reduces spin, and increases launch angle. This will increase carry distance.
MOI is the resistance of the club turning due to the ball striking the club, and basically makes the club more forgiving on off center hits.
