Really? Or did you mean to also say 'other than directly effecting launch angle on almost a 1:1 ratio'?

The 2 main contributors to Launch Angle are Angle of Attack and Loft. There's some dynamic tip bending which also plays a part, but is considered only an interesting spec for those that release mid-late or later.

I play a 13 degree driver, becuase my AoA is -4. My average LA is less than 10°. When I move to a 16° driver, my LA comes up around 3°, and spin goes through the roof.
