Who it is for

Advancing and competitive players looking for polyester with a firm response.

Why it works

Luxilon 4G Soft is a co-polyester string in 1.25 mm; the round profile gives it a predictable, even string bed.

Watch-outs

Polyester loses tension quickly and is harsh on sensitive arms — restring regularly and drop tension rather than pushing it.

Trade-offs

  • Tension drops with use
  • Gauge changes feel; try one step either way

Compatible player profiles

  • Intermediate swing speeds
  • Advanced swing speeds
