Federer's Aussie frame

[Dano]

Does anyone know what frame Federer is using @ the Aussie Open???
Looks like it could be a 2007 version of the six-one.
Also looks like a larger head:cool:

It's the (K) Factor series being released next month.

It contains new technology called [K]arbon Black, but still contains the nCode. It will be replacing the nSix-One. Fed is using the "Tour" version. Fed's frame is still 90 sq. in. There is a TEAM (nPS), and a 95 (16x18, 18x20) and a 95X, (27.5 in. 16x18) version, along with the Tour of the new (K) Factor series.
