Right now I am, and have been using a Prince NXG Graphite OS. Today I hit with a friends Babolat (He said they didn't make it anymore, I can't remember exact name, looked like a pure drive, same pj). I am not sure whether I should pursue a Babolat desire or stick with the NXG. I have heard good things about the Babolat's, and have had decent results with the NXG, but I don't feel like I am getting the power I need. Any help would be appreciated.
