When you bowl, you see oil rings on your ball. Look at the rings and if the rings are up next to your fingers, then your a high tracker, if the are low, more on the side of the ball, then you're a low tracker. If your rings go between your fingers and your thumb, then you're a full roller.
ya but what does this actually mean? does it just refer to how u throw a ball when u throw it? reason being i just gota black widow and looking at all the drilling layouts and dont know which one i am?
