I guess I'm the exception...the '12 caused me serious arm problems; it's been over 2 months since I picked up a racquet and every once in a while I still feel pain. I did have it strung with poly mains/synthetic crosses (50/53).
When I return to tennis (June, Lord willing) I'm thinking of using a Pro Kennex, Pacific, or Donnay.
Again, most people have said they have no arm issues with the Pro Open so it may have just been a problem that was going to flair up no matter what racquet I was using at the time.
But I'm going to move to something more flexy in the future.
