The racquet come with Luxilon Alupower Rough one of the best string on the ATP tour!! I have 3 Racquets to sale.Introducing the lighter version of Roger Federer's racquet! Call it a Holy Grail for those who want to experience maximum precision and sublime feel but in a lighter, more manageable package. With its speedy headlight balance, the Pro Staff 97 is designed to accelerate very smoothly and efficiently through impact. Of course no Pro Staff would be complete without Wilson's special Kevlar/graphite layup, a time-tested formula which lends the 97 its distinctively crisp yet slightly muted feel. From the baseline this racquet has been crafted to swing easier than Federer's RF 97, a fact that will enable a wider range of players to create effective pace and spin. The combination of speed and stability should make this a very user- friendly racquet at net. Factor in the compact 97 square inch head and classic Pro Staff feel, and touch artists should have all the ingredients needed to drop volleys on a dime. Intermediate and advanced level players who want to experience some of the surgical precision and magical feel of Roger Federer's racquet, but with a faster and more explosive feel will find it here.
