I've demoed a bunch of racquets, and my current favorites are the RDX300MP, iRadical OS, LM Prestige MP, Dunlop 300G, Volkl Tour 10 MP Gen II, Bab Pure Control 98, Wilson nPro 98, and Prince 03 Tour. If any of you can share good/bad experiences with these re: arm comfort, I would be most grateful. The stiffness of the Pure Control scares me a bit. BTW, I have demoed the PK 7G and found it a bit unwieldy, so I hope to try the 5G, Ki 5, and Ki 10 as well. Others I would like to try are the RDX500 Mid and the MP Tour 5, so any feedback on those would also be welcomed.
