Re: Which racquet brand do you use?
I used to be a Yonex boy (RQiS 1 Tour all the way!) but I've found new love in the Babolat Pure Strike 16x19. Had a nice, extended hit today and MAN that thing felt great. Just swing away and the ball found the court with extra spin. String plays a huge part of this racket though. I have a stiffer string in there, and I think a softer string is going to give you more of a cradle effect.
