Sadly, I have to say that I keep getting a lot of pain in my forearm, elbow, and wrist and I really believe that it is because of my racket/string combo. I used to just get over it, but now it doesn't go away. I need to change to something that is very arm friendly, and I have found that prince exo3 technology really is the best (in my opinion) for increasing arm friendliness. As far as string goes, I want to stay with poly. I have grown to dislike the feel of synthetics and multis because they are too mushy and lack precision in an open pattern. The tour and warrior lines are very intriguing to me. The rebel is too demanding and I don't like the 98 at all.
