4.0 baseliner/counter puncher, 32 years old. Used to play with the Pro Staff Original 85 for years, but the racquet has become way to demanding for me. Tried lots of different racquets, and ended up with the Babolat Pure Drive. I'm still adjusting, but over the course of long matches I feel much more "rested" afterwards. The racquet feels quite comfortable and great for groundstrokes and serves. The power boost has been evident, sometimes too much... I guess it takes a while getting used to it. Just wondering you Pure Drive players out there, what kind of strings and tension you use on this frame.
