With Black Code 4S, Tecnifibre gives big hitters a durable, low-powered co-poly with massive spin potential, impressive tension maintenance and great feel (especially for a firm monofilament). Boasting a square profile and sharp edges, this string puts a very tight grip on the ball. Topspin players will be able to hit high-arching, spin-loaded balls that come down sharply and explode off the court. For this string Tecnifibre uses Thermocore Technology, a multi-stage heating technique designed to soften the structure and reduce harsh impact vibrations.

My favourite string

Black Code 4s is much much different than the original Black Code . It feels more comfortable and give a nice pop and great control. Even when it loses its tension it gives more pocketing but still maintains control
