I'm a lifelong Wilson guy - strong 4.5, all court game, big serve - but for some reason, I have this urge to look at other lines. As I look at the specs for Babolat's Pure Drive and AeroPro lines - it does not appear that the specifications are all that difference -- a couple of tenths of an ounce in weight and a point or two in stiffness.... How does Babolat position the two frames? Do they say one frame style is better suited one a particular style of play? I'd REALLY like to know what Babolat has to say if anyone out there knows. Short of that - what is your experience?
