I have been using a Babolat Pure Control Zylon and my arm seems to hurt if I play twice or more a week w/it--I think it may be too stiff of a frame. I'm 6'3" with long arms and long fast stroke with a little top spin and big flat 1st serve--4.0-4.5 player. Of course it all comes down to how they feel when you demo but the ones I'm looking at are: Head LM Radical and Presige, Yonex RDX 500, Prince Diablo, Dunlop 300 or 200. I've always had Wilson racquets up to this year but they don't have any new ones I like. Any thoughts on these or other racquets for my style ? Thanks !!!!!
