Gamma Synthetic Gut. I am stocking this string in both 15L and 16 gauges. Gamma strings tend to be on the elastic side and this is no exception

Gamma Power Play 18 is an ultra thin composite of Kevlar, Zyex, and Nylon. When I played with the Wilson Hammer 2.7 95, a racquet with a dense string pattern and just a little too much power, this string helped me regain control of my shots. Pretty durable for an 18 ga too.

Gamma TNT has become the mainstay of the Gamma line. A very smooth playing synthetic. The 17 gauge version is a particularly nice performer. Durability is fairly average.

$24

Gamma Live Wire 16 has been around for several years, but until now I chose not to carry it. It's a lively multifilament that is easy on the arm and I expect it to fill the void left by the now discontinued tennis elbow string, Gamma RX.

$26

Gamma Prodigy 16 is a lively offering from the folks at Gamma featuring what they call coaxial construction in addition to their patented gamma irradiation process. The design is intended to provide the best of both worlds: the playability of a multifilament and the tension maintenance of a solid core string. Only in 16 gauge.

$27

Gamma Live Wire XP is similar in construction to the original Live Wire but with the addition of Zyex fibers the playability is crisper and the string is also more durable. In 16 and 17 gauge.
