Hi there, I just bought the Wilson Factor K-Tour racket (used by Lindsay Davenport - thought of course not), and I tried the hybrid stringing with the combination of Babolat Pro Hurricane 17 (mains) and Babolat VS Natural Gut 15L (crosses). Both are strung at a tension of 60 lbs. After playing with this racket several times, I find that I have less "pop" on my shots. And I can't hit as hard as I did with my N-tour racket, which was not hybrid-strung but it was strung also at 60 lbs. Is there something wrong with my choice of strings? Or do I just have to get used to it?
