[J.Warsoff]

Our team tested both a puncher and catapult design (when I was home for break). Last time I checked, I believe that we found the catapult was more accurate and consistent (Someone from my team correct me if I am wrong, as I haven't been at the shop since last Saturday.)

From what I can tell, a puncher has a smaller area of contact than the catapult during the actual shooting process. Since it is applying a lot of force to a small area, it causes much more deformation in the ball than the catapult, which can lead to inconsistency in the shooting (due to even the smallest factors like amount of air in the ball, location of point of contact, etc.) Once again, someone correct me if my observations are wrong.
