That being said, there are a few respected members here who currently either work in the industry, string on/or for the tour or have connections in the industry. But there is far more misinformation being posted as factual.
Nate Ferguson and Ron Yu of K1 who handles Federers rackets has confirmed that it is basically an of the rack k90 with custom pallets and a little lead at 12'. Good enough for me. Also confirmed by a very, very trustworthy poster with a HUGE collection of pros rackets, Equijet.
