So I've been playing with a pair of Head Youtek Prestige Mids for the last year or so. I love the racquets but I felt like my game has dropped a lot. I am unable to play as well as I used to. Quick description of myself: 4.0 baseliner. Lefty with a full western forehand and two handed backhand. I hit a heavy forehand and a pretty flat backhand. I've been looking at some racquets to try out and potentially buy: Yonex Vcore 97 Tour (330g) Yonex Vcore 97 Tour (310g) Yonex Vcore 89 Tour Dunlop Biomimetic F 3.0 Tour I guess I am somewhat looking for a racquet with some more pop as well as spin. I guess the Prestige mids have become a little too demanding for me (with it's dense string pattern and all). So I was hoping to get some help from you guys. You're all awesome! Thanks!
