The shorter Shafts will definitely help with Back troubles. When I feel mine Barking I put away the big "Dog" and hit the UW. Only Lose about 15-20Played 9 this morning, a good day to start out. Hit some good drives and hybrids, playing boogie golf. After 6 my back was starting to ache and I was standing up topping the ball. I think the hybrids are working well for me, hit them solid until 6. Greens were sanded and aeriated, so putting was not good.
