Who it is for

advanced, competitive players who want hybrid crosses.

Why it works

Co-polyester in a round profile at 1.18 mm or 1.23 mm or 1.27 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 3 gauges — 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
