We never got around to trimming the top of the shooter, so the students are holding it at an angle. It's not quite 45 degrees. There is a Lexan flap behind the shooter, that is being held down over the top of the ball before inserting the ball into the shooter.

It seems that the amount you compress the ball is a critical parameter. Too little and you get slip, too much and you waste energy. We are looking at about 1.5inch compression of the wheel on the ball. Can you share what you are using and how you calibrated it?
