Two models in the 2017 Ultra line feature Countervail (CV) technology (the Ultra 100 CV and Ultra 105S CV) which is exclusive to Wilson performance rackets. CV is an integrated frame technology that minimizes vibration without sacrificing performance and feel. According to a University of Minnesota School of Kinesiology study** tennis players using a racket with CV experienced up to 30 percent less vibrational energy from the racket and as a result of less fatigue 40 percent more control over their shots. In addition to maximizing player energy CV shortens recovery time after matches.
Extra string: It happens. Strings break sometimes quicker than you might think. It's always good to keep an extra set or two (or maybe even a reel) of your favorite string that you can take to a local stringer to get your racquet re-strung when you're in a pinch.
