What would happen if Nadal was forced to play with the Six.One 90? I believe this hypothetical question answers any doubt that racquet technology has great bearing on the one-sidedness of this rivalry. That Aero Pro Drive with RPM Blast absolutely scorches the ball, and in essence, covers far more court with its high forgiveness. This is a glaring advantage that Federer should not be so stubborn or naïve to, any longer. Consider this: Two out of three PGA Tour golfers carry an "R" series driver by Taylormade. The R7 inparticular, was carried by an uncanny, 75% of golfers in 2009.
