ProKennex updates the Ki 10 (305g) with a new cosmetic! Like the previous version, this racket offers a dangerous combination of spin, precision and power. At 305 grams (unstrung) and boasting an RDC swingweight over 325, this racket not only moves fast, but it also does a good job redirecting higher levels of pace. Like previous generations of the Ki 10, this racket benefits from Kinetic Technology which uses movable 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. This racket also comes with a firm Spiral Tech Carbon layup to create fewer impurities and air bubbles. The result, according to ProKennex, is a more stable and powerful feel when striking the ball. With this update to the Ki 10, ProKennex keeps a good thing going. Intermediate and advanced players looking to play aggressive tennis should love this one.  It's also one of the most arm-friendly rackets in its class!
