FYI, lots of information and video demonstrations related to this topic can be found on the spin transfer resource page.Fudging with the OB is big in banking. Gotta be able to lengthen banks, etc. Imagine what kicking would be like without english. Using follow/stun or draw is also big in setting up the non-pocketed ball from a combo. You see way too many beginners hose themselves on the combo. As BRussell said, "But maybe I'm completely wrong."
Enjoy,
