Players with lower PAPs in general have the advantage, because they are able to create better motion through the heads, and stronger break point because there release provides the ball a little more time to save energy. Typically Stacked leverage layouts are not good for spinners or players with lower tracks because it creates very unstable break points sometimes. usually 90% of the time a layout of 10.30 is best. I have a friend that has an axis cordinates of 2 over and 1' up. he has a few balls that look as if there laid out with label drillings for a lefty but this is infact a 4x2 or 5x2. also usually it's better to avoid using a layout that will require a weight hole. some spinners will track over the weight hole.
