The Pro Kennex Ki 30 255 is packed with plenty of features for a comfortable easy to hit frame that players with compact swings will love The Ki 30 255 is extremely light weight and responsiveness these improvements on the past several Ki 30 models concentrates on the moveable Kinetic Mass elements to the two four eight and ten oclock on the frame This serves two main purposes the first is to expand the sweetspot with a second benefit of increasing the torsional stability Our testers were pleased with the depth from the Ki 30 255 and the large sweetspot from the 117 Sq In head provided more than enough comfort for even the most tender elbow The Spiral Tech Carbon was a nice addition adding some flexibility and added vibration dampening to a racquet that is primarily constructed of stiffer highmodulus graphite Overall an excellent frame for players with compact swings looking for one of the most comfortable hits around
