A big part of the Wilson racquet line-up gets a makeover. In addition to the Wilson Roger Federer Autograph Pro Staff 97 and the Wilson Serena Williams Autograph Blade 104, it looks like also the Blade 98 will get the black and green paint job.
Specs are yet to be revealed.
Had brief communication with Wilson: these frames include something called Countervail that’s supposedly “maximizes a player’s energy and reduces fatigue. You won’t notice a difference in how the racket plays (it wont be stiffer).”
