I know that the tennis warehouse has a review, but their reviews generally seem to be nothing but praise for everything..! So I was wondering what you guys think about it? Is its light weight really *that* important? I've got the picture that a heavy racquet is the only way to go, so does that mean the Instinct just a bad racquet? I know Kuznetsova/Myskina/Gasquet use it (or the liquidmetal version but still the same weight) so does that mean this racquet is still good regardless of its light weight? What type of player would use the Instinct?
