The KI Q+5 Is and update to the Ki Q5 it features a lighter weight and Maintains ProKennex line of arm friendly racquets. Offering up stability even with a fairly thin frame this 100 Sq in. racquet feels steady and packs a punch. By segmenting the Kinetic Moveable Mass and placing it into the four corners of the racquet head, Quadfocused design increases the frame’s torsional stability even further, moving the sweet spot higher in the string face (as the mass of the frame moves higher, the sweet spot follows it). By stabilizing the frame’s corners, it will deflect less, increasing power and spin production simultaneously. Additionally, the special-treated spiral carbon offers improved dampening properties while the high modulus graphite provides strength and needed rigidity.
