They have various balls drilled at different spans, and they fit you as close as they can. They change the thumb slugs to fit you and you can tape it to get a better fit. You just tell them which ball you want to throw and they will fit it up with your size inserts and thumb slug. When you've thrown 1 ball you tell them you want to try something else and they will fit the next ball up in about 2 min's. It's good to try dofferent stuff without buying it.
