I am coming back from lateral epicodilitis and run up and down the forum searching for the most arm-friendly player's racquet out there! From the TW vibration frecquency charts The Prince EXO3 Tour 100 (18x20) lists second with 123 (points?) and 55 stiffness rating so it should be the best arm-issues racquet in production. How does it compare to the 16x18 version regarding softness? Is it that good for the arm? I will stay away from poly strings as I love multis anyhow. Would love to demo but I can't. So I have to buy based on reviews> PS: my babolats sweetspot felt smaller and smaller while developing tennis-elbow!
