The Pro Staff RF97 is no ordinary racquet. For starters it deploys crucial elements of Wilson's timeless Pro Staff formula, including a graphite/Kevlar layup, headlight balance and Perimeter Weight System. Taken together these features add up to a truly classic feel with world class precision. Even more impressive, however, is the man who helped design it. His name is Roger Federer and the RF97 was specially engineered for him. You will even find Roger's "go to" hybrid string setup along with his preferred tension and favored overgrip listed on the inside of the shaft. Unlike the Original 6.0 used by the young Fed, this re-invented Pro Staff has a wider, more rounded beam to better suit the power of the modern game. At 12.6 ounces strung, it should come as no surprise that this stick does not get pushed around. With its tour level stability and huge plow-through, the RF97 is the perfect weapon for trading heavy balls. Our playtesters were not only impressed by the phenomenal control, they also found plenty of power when they were able to deploy the mass. Thanks to the headlight balance, this racquet whips nicely through contact on full swings, a fact that should allow strong players to crank up the head speed when driving the ball through the court. At net the RF97 feels as solid as a rock. Even when the player is stretched out, this stick redirects pace with surprising ease. On serves, Federer's Pro Staff delivers all the control needed to tease the lines. Those who can swing it fast will be rewarded with some very weak replies. Ultimately, as the most modern and evolved version of Wilson's iconic Pro Staff line, this is a must hit for serious players. The fact that it was designed with the help of a true legend makes it a genuine collectible.
