Gamma tennis strings continually dominate all USRSA string surveys conducted in the USA. Gamma strings are also the only synthetic string to have claimed the #1 spot in playability for 23 straight years. Gamma Professional, a top of the line multifilament string that provides a natural gut feel, is also the only string to be rated higher than a natural gut in the overall category.
