Whether any pros are endorsing it or not I think the current Pro Staff v13 is a great racquet, and that's more important. The Blade might be more popular on the tour, but I preferred the Pro Staff. And I went into demoing thinking I wanted the Blade. Actually, I just demoed the RF97 too, and that's even better for me, but obviously, I can't get that one anymore cause everyone will think I'm a newb who only got it cause of Fed. And I am a huge fan of Fed, but that racquet, great as it is, comes with a certain reputation among the rec players. So, I'm getting a set of regular v13s instead. My point is, even if it weren't endorsed by Federer, I'd get it, and so would a lot of other people, at least enough to keep Wilson making them, but with his endorsement, they're obviously going to sell much more.
