Looking for a tennis string that assists with long, fast, attacking strokes? Take a look at the Yonex Poly Tour Strike 17g Tennis String...

This string is a polyester-based monofilament meaning that it doesn't feel as dead as regular polyester strings. It's also geared towards players who love to attack who are looking to add a bit more control to their game.

This set of Yonex Poly Tour Strike Tennis String is 17 gauge, it has an impressive level of durability (although if you're looking for serious durability, check out the 16 gauge version) and doesn't compromise on comfort either.
