Question

Does anyone other then Federer, on the ATP tour, use the Wilson K Factor KSix-One Tour 90?

Answer 1

I'm not fully sure but I think I saw some doubles players at the 08 Aussie Open using it.

It's hard to tell, because Federers version is really heavy Wilson have bought out a lighter version so more people will buy them. They both look exactly the same so it's hard to tell whether they're the same one that federers using or the lighter one.

Answer 2

I'm not sure.  Tennis Warehouse states that pros using that racket is only Federer.  Look -> http://www.tennis-warehouse.com/descpage... :)
