Who it is for

advanced, competitive players who want maximum spin bite.

Why it works

Co-polyester in a shaped profile at 1.25 mm gives this string its firm character. It is a firmer string built for control and bite, not comfort.

Watch-outs

Numeric feel ratings on this page are editorial, not manufacturer measurements. Firm full polyester is not a safe default for players under 13, for smaller juniors or for anyone with elbow, wrist or shoulder trouble — a multifilament, synthetic gut or a professionally chosen hybrid is the safer starting point.

Strengths

Firm bed holds a low, predictable launch
Sold in 1 gauge — thinner bites more, thicker lasts longer

Trade-offs

Polyester loses tension well before it breaks — restring on a schedule, not on breakage
Feel ratings here are editorial; the only real test is a session on your own frame
