A force to be reckoned with in the hands of the aggressive player, the 2019 ProKennex Ki Q+ Tour provides an optimal blend of power, control, spin and comfort. This updated model continues to feature Kinetic Quadfocus technology, which deploys movable mass around multiple points in the head to dampen the feel upon ball impact and improve stability and plow through. From the baseline, our playtesters found they could drive through the ball with ample power and heavy spin thanks to the racquet's stable and controlled response. Although our playtesters struggled to flatten out first serves, the high spin potential helped boost their kick serves and made it easy for them to place their serves deep in the box. Big swings on returns were rewarded with good depth and control. Overall, intermediate to advanced players looking to bring some added heat to their game should definitely check out this latest offering from ProKennex.
