With roots that extend back 40 years to the original Black Ace 93, this racket features the legendary engineering of one of the game's most experienced racket manufacturers. At roughly 335 grams strung, the Ki Black Ace (315g) is designed for the experienced ball striker who demands a high level of stability and precision. The feel is exceptional thanks in part to its 21mm straight beam and flexible RA stiffness. This racket also benefits from Kinetic Technology, a time-tested system that uses dynamic mass to help the racket plow through the ball more effectively. Other notable technologies include a Kinetic Comfort Handle System which reduces harsh vibrations for a cleaner feel at impact. In keeping with its innovative pedigree, ProKennex gives this racket FlexLogic to help it bend more optimally at impact. The upshot is reduced head deformation and increased dwell time, resulting in better control and easier access to spin. From the baseline the Ki Black Ace (315g) is great for trading heavy balls against big hitters. In addition to its stable feel at impact, this racket will give you the needed mass to drive the ball powerfully through the court. It also has an open 16x19 string pattern, resulting in plenty of spin-potential for bending and shaping the ball's trajectory. In addition to giving you excellent touch at net, this racket feels solid when volleying against higher levels of pace. With its impressive combination of stability, precision and feel, the Ki Black Ace (315g) is an obvious choice for experienced players.
