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 racket is not only appropriate for intermediate players, it should also work for the more advanced player who wants the extra power  and stability that comes with a 677cm² head size. Like the previous generation, this update has an extended 69.8cm 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 The Ki 15 also comes with a firm Spiral Tech Carbon layup to create a more stable and powerful response. Ultimately, the Ki 15 (300g) remains an obvious choice for those who want a more forgiving and powerful midplus racket. It's also great for the doubles player who wants a powerful serving racket with impressive pop and stability on volleys.
