The great Roger Federer's weapon of choice. The K Factor KSix-One Tour is one of the most traditional feeling racquets on the market. Just like its cousin the Pro Staff 6.0 from Wilson, the KSix-One Tour has a small head size and a heavy weight, offering superb amount of control. With Wilson's Karophite Black technology in the entire frame, players will experience more feel with more stability from this racquet. Also, the innovative [K]ompact Center is designed to improve maneuverability and handling, making this racquet very enjoyable to play with. However, this frame is not for the faint of heart (or stroke); players who use this racquet must have long and fast strokes and good technique to see any benefit from using this frame.
