With roots that extend back 40 years to the original Black Ace 93, this racquet features the legendary engineering of one of the game's most experienced racquet manufacturers. At nearly 11.8 ounces strung and boasting a mid 320's RDC-swingweight, the Black Ace 315 feels a tad more stable than the 300 gram version, but it still packs enough speed for the aggressive all-court player. As part of the new Ace Station series, this racquet's synchronized technologies are designed to deliver more control and feel than racquets in the Q+ and QuadFocus lines (both more power oriented). In addition to its time-tested Kinetic Technology, which uses movable mass to increase stability and power, the Black Ace features FlexLogic to help the racquet bend optimally at impact. The upshot, according to ProKennex, is reduced head deformation at impact combined with increased dwell time, giving the shot-maker heightened command over the ball. Other notable technologies include a Kinetic Comfort Handle System which reduces harsh vibrations for a cleaner feel at impact. From the baseline the Black Ace 315 combines outstanding ball feedback with very easy targeting on full swings. It comes around fast for the weight while managing to feel stable against higher levels of pace. It's also very spin-friendly, and the touch on volleys is spot on. Aggressive servers will have enough control to swing for power. With its impressive combination of stability, precision and feel, the Black Ace 315 is an obvious choice for experienced players.
