Get comfortable with your driver swing. Its definitely a different swing than the irons. Make sure you're playing the ball from your front heel and make sure you're not to close to the ball. i find a lot of players are pulling across the ball from the outside in to towards the body to get some swing speed. They put a lot of horizontal spin on the ball and can't seem to get away from the slice. I always recommend someone bring a 2x4 to the range and force yourself to swing inside out, or the line closer to your feet then out. I promise when you wack a 2x4 with a club you don't wanna break a couple times you will learn to change your swing plane. A drawn ball will fly longer and release more because of the balls spin. I added around 40yds to my long ball when i switched to playing a draw in college. I just switched from a R11 to a Ping G and added about 30yds and a huge amount of accuracy to the long ball.
Hope that helps a little.
