i have switched to 100 square inch pure drive. Cold damp day, ball really not moving and getting increasingly frustrated about inability to generate any pace. So I switched to an old cheap oversized light racket. it was like being given a rocket launcher compared to the heavier bat, I could blast winners off placeless nothing balls and I was hitting clean through our opponents. The difference was the racket head speed I could generate with the lighter racket, I am beginning to doubt the wisdom of using a heavy bat, the extra weight just slows my arm down too much.
