After playing with a Volkl Tour 7 (11.4 oz with overgrip) for about 5 years and finally realizing that it is too heavy for my imposing 140 lb. aging body, I demoed a 10.4 oz racquet and discovered that I could actually smash an overhead, something I could not do with any power with the Tour 7 because of the heft. I can also serve with better pop and spin with the Volkl BB 5 because I can snap my wrist with the lighter racquet. However, after three sets with the lighter stick, my wrists were very sore the next day. Is this to be expected with any lighter stick that you can snap your wrists with? Thanks for any insights based on your experiences.
