Pro Staff 97 Countervail. A lighter, faster version of Federer’s RF97 Autograph, a user-friendly entry point into the legendary feel and precision of the Pro Staff universe. Pro Staff 97 is made with Countervail, a material technology designed to reduce impact vibration and the resulting muscle fatigue. This racquet offers decent stability at impact, but at 7 points head light, it whips through contact with surprising ease. The crisp feel is punctuated by exceptional vibration dampening and excellent ball feedback.
