This comfortably firm and low-powered string gives experienced players the needed control to attack the ball with their most powerful strokes. Loaded with bite, Polylon 17 is not only extremely spin-friendly, but it also has very impressive durability for a thinner gauge. With its low price, this is one of the best value polys available. A must hit for big hitters on a budget.

What players say

Mixed 2 sources

Tennis Warehouse's playtest and customer reviews agree Gosen Polylon 17 is a firm, control-first budget poly with strong durability, best suited to big swings. Opinions split on spin, feel, and tension maintenance, with several customers calling it underpowered, dead-feeling, or weak on spin.

Best for

Big hitters with fast, full swings
Control-oriented players on a budget
Durability-focused string setups
Crosses in a hybrid with a spin-friendly main

Pros

Rated highly for control (92/100) by Tennis Warehouse playtesters, who called it predictable at high swing speeds
Very durable for a budget poly; one playtester got two full weeks of hitting, and customers confirm long life
One long-term customer reports it is the only poly that causes no muscle soreness after hours of play
Playtesters found spin easy to generate with fast, aggressive swings

Cons

Low power (44/100 in Tennis Warehouse scoring); multiple customers call it underpowered
Some customers found spin disappointing, with one saying flatly "there is no spin"
At least one customer rated tension maintenance only fair, saying it loses snapback after a few hours
A traditional, firm poly feel that Tennis Warehouse says is not suited to players with a history of arm issues
