A great 'tweener that offers good stability in a lightweight package. This Ki 15 has an updated cosmetic. We found some useful pop from all areas of the court with racquet head speed easy to generate when needed. The Ionic Ki 15 makes a solid choice for the all court player or the doubles specialist who can exploit the maneuverability and power of this racquet. At net we found plenty of pop to finish off the point, while still finding good feel and control on touch shots. Players with moderate swing speeds found they could bring this racquet through the contact zone with good pace on serves and overheads. Fans of the comfortable feel of ProKennex's Kinetic system and the Pro 15G (predecessor to the Ki 15) will find an even greater sense of comfort and dampening from the Ionic technology in the Ki 15. If you are a 'tweener racquet fan, then the Ki 15 is a must playtest. Best suited to players at the 3.5 to 4.5 level who use a medium pace/length swing.
