I have been playing with Head i.Prestige Mid 3 years. I'm experienced player ( can't tell my grade according NTRP since don't know what is NTRP - I don't live in USA). Already a few months that I have started to feel weakness in my elbow tendon. I understand that best racquet is heavy, flexible, headlight, not oversize, not so long and etc.. Prestige Mid must correspond. I understand that it is not possible completely eliminate torsional force appearing during impact shocking our elbows. Anyhow I read Pro Kennex has kinetic system in the handle, Wilson uses TRIAD, Babolat has double woofer. These techniques surely if not completely but partially reduce elbow shock. At the same time I didn't hear anything serious from Head, Yonex or others regarding this matter apart of frequent changing materials for obtaining more power. Frankly speaking, I don't think that other producers forgot all these problems with elbow and their racquets are much worse. In this regard I have 2 questions: 1. Maybe really I'm wrong and some player's racquets are much better for elbow than Prestige ? Can you advise must we believe that some technologies really made racquets of some brands much better and softer than racquets of other producers ? 2. Do you recommend shifting from 12.1 oz. Prestige to another 10-11 oz. player racquet in this situation with elbow? Thanks in advance.
