String Hybrid
what is the difference between Gamma Infinity 15L Hybrid Tennis String 16g and gamma infinity?
This is the gauge string. A higher number = Thin string. Thinner strings tend to have more feel, but they break more easily. Thus, the 15L is a little more severe than the 16 but will last a little longer. In addition, the L stands for "light". It's a real thinner than 15 gauge strings, but still thicker than 16 gauge.
