Wilson makes impressive changes to the Pro Staff 97 ULS but keeps the winning formula that made this such a perfect racket for beginner and intermediate level players. In addition to giving you easy access to pace and spin, this racketR019s design was deeply inspired by Federer's racket. Like FedererR019s iconic RF 97 Autograph, this racket has a sleek tuxedo appearance with an innovative black velvet finish. It also features the same meticulously detailed chrome touches and laser engraved graphics. The result is a racket that not only has a unique look, but it feels wonderful in your hands as the racket is spun and repositioned in anticipation of the next shot. Like its predecessor, this version of the 97 ULS is extremely maneuverable - a fact that will make it easy for less advanced players to control the racket's speed and angle through contact. On groundstrokes this racketR019s speed and precision will give you the confidence to swing bigger when applying pace or selecting ambitious targets. The 18x16 Spin Effect string pattern supplies a nice combination of bite and directional control, resulting in very easy access to spin. The light weight is also helpful on serves where the 97 ULS accelerates with remarkable ease to deliver a very accurate ball. Wilson has not only developed a racket that will make it easier for you to play more aggressive tennis, but it comes with cosmetic stylings that were developed in partnership with a legend.
