I don't understand how you can say this? So are you basically suggesting that spin only affects the angles off the rails, and not the overall distance the CB travels?C.Milian...Nothing prevents anyone from understanding the vertical axis. Set up a 30 degree cut shot. Shoot it into a pocket, aiming at dead center, 12:00, or 6:00 on the CB. Note where the CB goes. Shoot the same shots and add sidespin. With the same speed stroke the CB should go virtually the same place. It will just respond differently off of the cushion, due to the sidespin.
