Ways to make a ball delivery system, based on a back/down swing.

I'm having trouble making a ball swing and delivery system Im happy with. I don't have the experience with the full gammut of classes or ways to build something like this.

The idea is to have the user involved as much as possible emulate something like a bowler backswing and downswing with a fairly speedy release velocity. Add I the ability to control the spin etc after release.

The flick -hook idea is a possibility but it would have to have a back swing element to it.
