So I decided to switch to an MP. But I still held on to one of my prostaff mids. I find that unless I am playing someone who puts a lot of topspin or someone who is a half or more level ranking higher than me, the prostaff mid can handle the situation. I do not feel any of the elbow pain when I play someone my level or slightly lower primarily because I dispose of them quickly by attacking the net. Its only when I play someone with an extreme FH grip or someone better than me that I end up working harder and feel the effects of the a) smaller head and b) stiff racquet. My solution - use the PK 5G or 5G PSE (depending on my mood) against the better players and stick with the 6.0 mid for players the same level or slightly lower. Anyone else have similar problems or are in similar situations? So in response to the person who asked why buy many frames (or whatever it was), the answer is need for versatility due to lack of adaptability.
