Have you played with the both the Volkl V1 Classic and Volkl V1 Organix OS? I'd like to compare the 2 please. I'm not looking for specs. No disrespect intended: I can find specs for myself. (I know the OS has a larger head.) The comments on TW for the Organix V1 indicate it's easy on the shoulder. I'm hoping to hear from some of you, especially anyone who has shoulder problems. I've had shoulder surgery twice. I'm looking for a racket that is easy on the arm and especially the shoulder. Thanks!
