#3 - TEE POSITIONS
Changing the tee position can either be used to adapt to how you hit a driver or to adapt to a particular shot on the course.
Get on the range with your driver and hit ten balls from each of these tee positions and see what the results are. If you tend to hit up on your driver, a high tee will more often than not be better for you and similarly hitting down on a drive will require a lower tee height.
If you hit up on the ball a normal or low tee height will cause you to top the ball. With a player who hits down on a drive a high tee will cause the club to get underneath the ball and shoot it high up into the air.
For a drive into the wind many amateurs feel they need to tee the ball low to nullify the gusts, but in fact this will cause extra backspin of the bottom of the face and stop the ball while in the air.
Again this is about practice so it may help you to tee the ball in a medium height position when into the wind but higher when playing a shot when the weather is calm.
