Wilson offers a game improvement racquet which is a class leader when it comes to control in the KOne. The flagship racquet of the K Factor line, the KOne features Wilson's (K)onnector technology. Two external wings molded onto the side of the hoop at the 3 & 9 o'clock positions comprise the (K)onnectors, which are designed to increase the dwell time of the ball upon impact, providing greater control, comfort and a larger sweetspot. For improved mobility, the racquet features Wilson's (K)ompact Center. A reduction in the size of the yoke (the "Y" shaped area between the handle and head of the racquet) provides additional feel and is the result of direct feedback from Roger Federer. Through the use of Wilson's proprietary (K)arophite Black construction, Wilson claims the racquet also offers more feel with more stability and a stronger response compared to its predecessors - a claim which left us with no doubts during on court testing. There's ample power for deep hitting and we found a greater sense of depth and directional control compared to other racquets with a similar power level. The racquet feels very mobile from all areas of the court. At net we found a very solid response at impact, a controllable level of power and a generous sweetspot. Spin is easy to generate with this one and on court testing revealed plenty of grip from the slightly fanned pattern of the stringbed. This impressive game improvement racquet is a must demo for beginning to intermediate level players as well as stronger players seeking some controllable power.
