I know Tiger talks about controlling distance a lot with "traj" (trajectory). I'm sure everyone does this, but I just recently watched a Tiger Woods and Anthony Kim golf clinic on youtube (http://www.youtube.com/watch?v=TxOIO6QTnRw), so it's fresh in my mind. Since the pros are good enough to hit the sweet spot on the club every time, they can get a very precise distance reading for each of the their clubs. So choking up or down and hitting it on a higher or lower trajectory to add or subtract a few yards and they are able get distances spot on.
A little off topic, but the funny thing about the clinic shows why Anthony Kim fell off the face of the planet. His work ethic and knowledge seems next to zero.
