I'm curious if loyal fan of the Wilson Pro Staff have made a switch to Yonex VCore Tour 89 racquet. I've always been a fan of the PS because I'm a fan of Pete Sampras and I like the frame of the PStaff. I've never used any other racquet other than the Wilson. Having said that, I want to try something new in hope it would give me a better advantage over the PStaff. My question is if you made a switch to say Yonex Vcore Tour 89 and never looked back.
