Federer's RF97 vs Retail

I know, I know, this topic has been beaten to death. With the swiss maestro winning Wimbledon once again, it's safe to say he's playing better now than he ever has. With another win people begin to debate if his frame is the retail RF 97 or some racket forged in the fires of Mount Doom by Sauron himself.

I want to open the debate once more. This is all based on the credible evidence I have found on the interwebs. My opinion is, it is similar to the retail version, but not exactly the same....
