This racquet is Sony Smart Tennis Sensor compatible.
For old-school feel and comfort with modern performance potential, try the Wilson Pro Staff 97S. Featuring Spin Effect Technology with a 18x17 string pattern, the 97S allows for extreme spin creation without sacrificing control and feel. The cosmetics are different at the request of Roger himself as he wanted his racquet to look unique. Many tour players use the Pro Staff line, however only Roger uses the RF97. As part of Wilson's "Attacker Player" segment, the racquet is composed of braided graphite and kevlar for the solid feel you've come to expect from Pro Staff models.
At 11.4 ounces strung, the 97S is just under a full ounce lighter than Roger Federer's new RF 97 Autograph frame. It is also exceptionally maneuverable dispite its 6 points head light, up from 3 points head light from the previous edition. This model will no doubt provide the spin, feel and shot-making ability experienced players are seeking.
