Yes. AoA is angle of attack.

 

Ok, so if I have a club with a dynamic loft of 30* and an AoA of 2* how do I increase the spin if the dynamic loft does not change, since I have read that a more negative AoA does not change the spin rate if the loft is the same. Also is it true that hitting up on the ball with a driver does not decrease the spin rate, its more where you hit it on the face, high on the face will decrease spin and lower on the face will increase spin.

Spin loft is very simple.

 

Assuming the same contact and clubhead speed and a matching face/path and all that

 

1) Delivered loft of 25, AoA of -2 = Spin Loft of 27°.

2) Delivered loft of 25, AoA of -6 = Spin Loft of 31°.

 

You can hit up on the driver but keep delivered loft down to reduce spin. Again:

 

1) Delivered loft of 10, AoA of -2 = Spin Loft of 12°.

2) Delivered loft of 10, AoA of +5 = Spin Loft of 5°.

 

Yes, vertical gear affect can ALSO affect spin rates, but again, we're talking about same contact, clubhead speed, yada yada etc. etc.

Got it, Thank you.
