assuming you hit it on the sweetspot everytime, how much difference in distance does a 43" driver make compared to 45"? If you switched from a 60g shaft to a 100g shaft, how much difference in distance would that make?
So, I may lose only 5-6 yards, but with a real good chance to hit the ball a lot more consistently. Seems like a good move. Of course, I know the difference in swing weight, the effect on flex all need to be accounted for...
