Tourna Black Zone

Yes, it is specifically designed for hybrid setups. The ultra-smooth surface reduces friction, allowing the string to slide easily against softer crosses like natural gut or multifilament, which helps improve snap-back and overall playability.

While it is a firm co-polyester, it is engineered to offer a more comfortable response than many traditional stiff polys. You get the durability and control typical of a monofilament, but with a slightly more forgiving feel during impact.

The 16G (1.30mm) is thicker, offering maximum durability and a slightly stiffer feel, which is ideal if you break strings often. The 17G (1.25mm) is thinner, providing a bit more feel, spin potential, and comfort at the expense of some longevity.

Because of its slick, low-friction surface, this string promotes good snap-back, which is essential for generating spin. However, it is a round string, so it relies more on your swing speed and technique than a textured or shaped string would.

Like most co-polyester strings, it will lose tension over time, but its refined construction helps it hold tension more consistently than many entry-level polys. It is a reliable choice if you want predictable performance throughout the life of the string job.
