Diadem Solstice Black Reel

The star shape creates a low-friction surface that allows the main and cross strings to slide easily against each other. This movement generates significant snap-back, which is what gives you that extra bite on the ball for increased spin.

Yes, Solstice Black is designed as a soft co-poly, making it much more comfortable than traditional, stiffer polyester strings. It is a great option if you want the control of a poly string but need something that is easier on your arm.

The black pigment used in this version actually alters the chemical composition slightly, resulting in a noticeably softer feel at impact. It also benefits from an improved extrusion process that helps the string hold its tension longer.

Thinner gauges like 18 (1.15mm) offer more spin and feel but will break faster, while thicker gauges like 16 (1.30mm) provide better durability and control. If you are a heavy hitter who breaks strings often, start with the 16 or 16L gauge.

While it is designed for players of all levels, it is specifically built for those who want to add spin and control to their game. If you are a beginner, ensure you are comfortable with the slightly firmer feel of a co-poly before making the switch.
