I've never had elbow pain, and I use stiff rackets (like 70; 25 mm beam). I don't believe I have trouble with any of my strokes, and I think that's where most of the injuries come into play. So I guess I'm just a little confused when people say they get tennis elbows with certain rackets, but not others. Isn't it more a function of your technique and physique whether or not you're hurting after 3 hours? Also I would modestly consider myself a 3.5-4.0 player, depending on the day. I would also consider myself stronger than the average player at my level. Although I've had my experience with bigger head size rackets, I like player's racket a lot more. My current racket is pure storm tour, and I want to try out the k6.1 95, which I doubt would give me any trouble. So another thing I'm wondering is how does racket weight even matter? If you're stronger, and can handle a 340 sw, what does the player's level have anything to do with it?
