like was said already. more info is needed, the more the better.
what if 2 people ask the same question?
one has a low tilt and the other is a spinner. one might then need a virtual gravity and the other a much more mild ball.
the best info you can give is pap, speed, revs, and lane conditions, and lane surface.
