The ProKennex Ionic Ki 15 PSE is a powerful racquet that is very forgiving on off-center shots, due to the generous sweetspot and 105 square inch headsize. This racquet uses new Ionic technology. Jetron is an inelastic composition of ionizing carbon structures that neutralizes charges in the frame at ball impact, which increases the energy transfer for more powerful shots. ProKennex Ionic Ki 15 PSE has also implemented some small micro-bearings at the top of the frame. These micro-bearings transfer energy as the racquet strikes the ball, which results in more pace. The micro-bearings have an added benefit of neutralizing some of the unwanted vibrations.
PSE is short for Pro Special Edition and is better suited for more advanced players than the standard Ki 15 version, but players do not have to be pros to take advantage of the Pro Special Edition. Players at the 4.0+ NTRP level and above looking for a little more racquet, get 105 square inches and a generous sweetspot. This racquet is versatile and handles well at the net and baseline. It is perfect for slices as the chance of touching the beam is low as the width is only 25mm. There is a good feel on drop shots and the 16x19 string pattern really gives players the chance to develop some serious top spin.
