Wilson [K] Factor [K] Pro Staff 88

Wilson's [K] Factor [K] Pro Staff 88 is a mid-range racquet that is a redesigned version of a classic racquet once designed for Pete Sampras. By modern standards, the headsize is small, at 88", and its strung balance is 6 points head-light. The Pro Staff 88 emphasizes control and precision as its main features. It uses Wilson's "Karophite Black" frame construction to enhance the graphite's strength. This racquet is also heavier than many of the other [K] series, coming in at 12.9 ounces. This racquet is better suited for advanced players with a longer reach.
