We had some luck using mini CIMs. I think you'll have the ball inconsistence issue regard less of which motor you're using. I know a used ball have a different trajectory compare to a brand new ball. I think you really need to take some time to find the sweet spot for your shooter. Don't go for the long shot. Dial in your shot at the base of the castle, that should give you a few more points per cycle. Good luck prototyping and enjoy the process.
