Abstract
A tennis racquet having a bipolar weighting system, comprising a headweight and a tailweight, is shown to outperform all racquets known to prior art. The racquet is very head-light (15 points) and has a high swingweight (350), while it weighs under 400 grams. A series of high-bounce plastic string pads serves to improve stringbed life and bounce.
