How are your PSL GT stability issues? Does a little lead tape go a long way on this racket? I currently hit with a Wilson K 6-1 95 and the racket offers wonderful comfort and stability. I demo'd the Babolat PSL GT twice and like the lighter racket head for generating topspin. The PSL GT felt a little unstable on off center hits and volleys (yah I do that sometimes). I am a 4.5 with long strokes and a SHBH. All court and like to S&V.
