Got my butt kicked last night by a 61yo guy (I'm 50) in doubles. He is a former tour player from Australia who now plays for the US in international competitions. He was using a Babolat Pure Drive, as do a lot of the top 50 and over guys around here. I'm always amazed by that, I thought the frame was for younger guys, but now I'm seriously thinking of trying it out. Curious if this is true in other areas of the country.
