I demoed a few rackets and decided I liked the Head YOUTEK Prestige Mid the best and I was planning on getting it, until a though recently just popped in my head. Should I just stick with my current racket? I have been using it for two years and it is the Wilson nTour Two nCode? I haven't really had any problems with it, it's just that I felt that hey maybe I should get a new racket. I mean a racket can't make that big of a difference in your game can it???
