This morning Federer was with a couple of friends at the court, his rackets ware strung by the morning, and the specs are right. About sw I cannot tell you since it was not checked, but from my calcules it is around 360 to 370, another funny thing is that 2 or 3 players play with his racket but only for 5 to 10 minutes, then a guy from wilson or so, came and ask for the rackets! This was what my friend tell me, it seems that they don't want the rackets to be tested by anyone.
If this is correct I believe that the rackets sent by wilson to Greg, saying that thoses are the real Federer's rackets, it would not be truth, maybe something similar but not the real setup that Federer is using.
According to my friend theres a lot of secrets about his rackets and even talking with the Fed's team, they don't want anyone to know the truth.
They just keep saying: "...that's closer to what you can get in stores...".
Marketing is the key, not the truth about it
