We have a traditional flywheel like you have. We used 6" diameter wheels from Skyway. The compression of the ball depends on the angle of your shooter and the distance of the wheels. On our shooter there is about 1.5"-2.5" compression throughout the hood. I have seen other shooters that is alot more. We are still debating between using a miniCIM or a 775pro with a versaplanatery. You want more backspin if you are shooting close to the tower and our RPM has been between 6 and 7 thousand which gives that to us.
