MoneyBLong: I'm wondering if anyone has advice on the use of spin off the tee?
In general, using 3/4 to full backspin off the tee will give you the most distance. This varies according to the wind and the course. For example, a lot of times you can get more distance on your drives at St. Andrews or Royal St. Georges if you use less backspin but hit the fairway mounds just right to kick the ball forward.
It also varies depending on the Trajectory of your driver (eg. med/high vs. high) and the Spin of the ball you use.
Try experimenting with different amounts of backspin off the tee and see what works best for you, your ball, and your driver.
