Never had this shoulder pain before until I just tried the Voltric 80 for the first time. In the past, I've used a lighter racquet particularly Armortec 500 on a regular basis. I'm not sure if all those years I was able to get away with inaccurate techniques or if my body was in shock after using a heavier head frame racquet for the first time, but in any case my top shoulder(at the joint) pains like crazy. I can barely move my shoulder up. I'm now debating if I made a mistake in getting the VT80. Wondering if I should give it a few more tries(after my shoulder is rested) or fear of recurring the same pain again. Or should I sell it and go for a less stiff racquet. I like to hear your feedback or suggestions.
