Please just stop. Luxilon makes synthetic filaments first, tennis strings second. Their products sell themselves because of professional use. That is not remotely a relevant comparison.
Stop what? I am not comparing ltec to luxilon. I just found it curious. The luxilon expert has swore up and down over there that a tennis ball does not have enough impact to change the elasticity of their strings. That the composition is much sturdier than that based on their testing. They claim to have the science.
