This tennis racket string would have half an elipse(down major axis ) in cross-section . The straight side of the string would be filled with hooks , like in velcro . The oval side would remain smooth .
When strung in the racket this string makes the racket have two sides with completely different stroke properties allowing players a wider choice of shots . speed / straight versus slower /spinnier
? Just an idea . Although, you would have to be good at spinning your racket .-- wjt, May 15 2008 US6117383 http://v3.espacenet...C&IDX=US6117383&F=0tennis racket string with textured surface [xaviergisz, May 15 2008] Not bad-- GutPunchLullabies, May 15 2008 Put double sided sticky tape on my ping pong bat once.
