Where it wins and loses

against the average for this category
Strengths
Polyester: the most spin and the best durability of the string types
Thick at 1.30 mm — the durable end of the range
Shaped profile (textured) — the edges grab the ball rather than sliding across it
Trade-offs
Loses tension faster than any other material, and the least forgiving on the arm
A thick gauge gives up some spin and feel for that durability
Shaped strings notch and saw against each other faster than round ones
