I'm looking for a recommendation from somebody who hopefully has tried both frames for a bit. I recently demo'd both frames from a local shop but ran into a few problems that is making my decision difficult. I really liked the Aerogel 500 Tour however I didn't get to try any serves with it because a string broke while using it. Went to trying the Pure Drive which felt decent but it was strung with a hybrid of Luxilon Big Banger and Wilson NXT and it felt alot different than the string setup I use (Tecnifibre NRG2). I could tell the racquet was more powerful than my current frame but it felt a little harsher than what I expected.
