ProKennex updates the Ki 15 (300g) with a new cosmetic but keeps the impressive playability of the previous generation. As the heaviest Ki 15 model, this racquet is not only appropriate for intermediate players, it should also work for the more advanced doubles player who wants a powerful serving racquet with impressive stability on volleys. Like the previous generation, this update has an extended 27.5" length, giving it extra pop on serves and groundies. Comfort is impressive thanks to the Kinetic Technology, which deploys dynamic mass in the head to reduce the amount of shock that reaches your arm. Other arm-saving technologies include a Comfort Cap, which adds Kinetic technology to the butt cap to attenuate residual vibrations. Ultimately, the Ki 15 (300g) remains an obvious choice for those who crave comfort and power.
