If it works for you, that's great. People seem to equate the Clash's flex with it being the cure-all for elbow and wrist issues. Balance, grip and mechanics I'd say have as much to add to the equation. My wife, for instance, has been using the Clash 100 and she's developed wrist and elbow pain. We went to a trusted pro shop owner with over 30 years experience, and they said the Clash's flex could, too, strain wrists and arms by being too flexy. Have to find the right racket balance, weight and string setup.
