I thought the ONE THING that we were all in agreement on was that the Tour 90 was originally designed specifically for PETE SAMPRAS, and NOT specifically for Federer. That's why the Tour 90 is predominately black in color as Pete told Wilson that he will only play with a racquet that was predomintely black. Wilson made it swing heavier than the PS 6.0 85 so that Pete wouldn't have to use so much lead tape on the head. Of course, this was all before Pete abruptly decided to retire. When that happened, I think Wilson made Federer the poster boy to promote the new Tour 90. Had they made the Tour 90 for Federer to begin with, they would have made it red in color as I understand that's Federer's favorite color. That's why the nSix-One Tour is red and white (like the Swiss flag). This one IS supposed to be made for Federer.
Let's assume the above quotation is true, then what will be the difference(s) between the Pro Staff Tour 90 and the new K Factor Pro Staff (apart from the 'K Factor' technology)?
