The shaft of your driver is eight to ten inches longer than the shaft of your short irons, so you need to adjust your stance in relation to the ball, because the bottom of the swing arc varies with each club.
· The longer the club, the farther forward in your stance the ball should be.
· For middle irons place the ball in the middle of the stance.
· For long irons and hybrids, the ball should be an inch closer to the target.
· For a driver, it should be approximately off the heel of your front foot.
(Tip: The logo on the left chest of a shirt is about the driver ball position).
