The ProKennex Ionic Ki 20 is a game improvement racquet that weighs only 9.3 ounces when strung. This is an extremely lightweight racquet, which makes it very easy to maneuver and make last second adjustments to the strokes. Players also get a racquet head size of 110 square inches, so this is an ideal racquet for beginners or for intermediate players with short strokes and a low swingspeed. There is plenty of power in this racquet and a big sweetspot. The open string pattern provides players with the opportunity for lots of spin, but if the racquet head speed is too great then the power will be difficult to harness and the ball may end up past the opponents baseline.
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. This Ionic technology adds as much as 56% to the efficiency boost and that is something every player should notice right away. Micro-bearings are inserted in the top of the frame and is a Kinetic System Technology. Every time you swing the racquet, these Micro-bearings move back and forth. At ball impact energy is released and that is transferred into power.
