Who it is for
advanced, competitive players who want hybrid crosses.
Why it works
Co-polyester in a round profile at 1.15 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
Compatible player profiles
- Advanced swing speeds
- Competitive swing speeds
- Spin-focused hitters
- Control-first hitters
