my doc (he is a tennis player in age 50) suggest me to take month rests and play flexier racquet (like prokennex). Actually, I have ProKennex Ki5 and Rendondo, seems better on my shoulder before.
BTW, I replace the grip to Babolat skin feel http://www.tennis-warehouse.com/Babolat_Skin_Feel_Grip/descpageBAB-BSFG.html
For the original grip, size is definitely smaller than Head, Wilson, Babolat, Volkl, ProKennex (I compared this many times in shops and my other raqcuets). Putting overgrip on, feel bevel round.
Now with overgrip on Babolat skin feel, can feel bevel, and size match grip3.
BTW, I have no dislike in this (honestly, 15mm beam give u magic maneuverability, feel/ball pocketing is good), just my age and shoulder cannot handle
