Who it is for

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

Why it works

Tecnifibre Black Code 4S is a co-polyester string in 1.20 mm and 1.25 mm; the shaped profile gives it a spin-oriented string bed.

Watch-outs

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

Strengths

Firm, controlled response
Extra bite for spin

Trade-offs

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

Compatible player profiles

Advanced swing speeds
Competitive swing speeds
Spin-focused hitters
Control-first hitters
