I am 5'7'' weighing 160 lbs at 48 years old, and had a moderate swing speed around 100 mph. To increase my distance from the tee, I have been using a 910 driver, 3 wood and hybrid that play at 46 inch length. I average about 250 yards from the tee with my driver but the club feels heavy and I have very little ball control. I was considering going with a shorter shaft with a playing length of 44 inch's with a 62 gram shaft weight. I have been following the TPI workouts all winter and have seen increased club speed and now at 106 mph. Will a shorter shaft benefit my game?
