What's really going on under that paint?

Or so this is what the public eye thinks...but is it really what it is? Roger Federer has been with Wilson since his rise to the top of the men's tennis world.

When he first stormed onto the tennis world people thought he was using the Pro Staff 85 (Same racquet of choice for former world #1 Pete Sampras) Which he was, it was the version made in China and contained lead.

After that, supposedly He was using the Hyper Pro Staff 6.0 Tour....but under that paint job was still the Pro Staff 85. Federer finally switched over to the Pro Staff Tour 90, but kept the Hyper Pro Staff 6.0 Tour Paintjob.

Eventually after the pro staff tour 90 he switched off to the N 6.1 Tour 90, people long speculated that it was again a paintjob, but a playtest from Greg's Racquet Service proved that it was infact an Ncode  6.1 Tour 90, but had been modified for Roger Federer himself, and from that RF version the retail Ncode 6.1 Tour 90 was spawned.

Later on Federer switched over to the K Factor K6.1 Tour 90, which Wilson claimed several times over was the actual retail racquet you could buy off the shelves. But was it? Sources claimed that Federer had has personal frame designed with a softer graphite, and depending on the surface lead was applied in the handle.

And now he's switched to the BLX 6.1 Tour 90...but what is this one? I will continue investigation and let you know.
