Based on Federer"s Pro Staff Six One 90, the Wilson Pro Staff Six One BLX 95 adds a new specification to the Pro Staff family. Offers a slightly lighter feel than the 90, 11.6 ounce strung weight and a thin 18mm flat beam. Legendary braided graphite construction combined with new Amplifeel handle system for the best feel yet in a Wilson Pro Staff. Continues the use of Basalt fiber (BLX) technology for improved feel and frame feedback, continuing to feature classic feel in the same tradition as the previous-generation Pro Staffs: nSixOne Tour 90, Hyper Pro Staff Tour 90 and Pro Staff Kevlar 85. Same flat beam design as previous Tour 90"s, providing the ultimate in feel and control in a more forgiving 95 sq. in. head size. Expect the ultimate in control, feel, and frame feedback on the market today. A great versatile option for a broad spectrum of intermediate to advanced players with more developed strokes.Racquet Specifications:Headsize: 95 sq. in.Length: 27.00 in.Weight (strung): 11.60 oz.Stiffness (Babolat RDC): 65Balance: 12.60 in.
