First off, I tried to search on this question but just got overloaded with PST and PSL threads. For anyone who's owned both, can you tell me the difference? I tried to demo my way through, but one of the demos came with Poly so it wasn't a valid comparison. I have to say the GT looks so much better and has a normal tennis racquet finish. The old model's paint and graphics are horrible. If I wind up the old modesls I'm going to sand them down to the graphite and clear coat them.
