Diadem Sports Flash Reel

While it is a co-poly string, which are generally stiffer, Flash is engineered to offer a more comfortable feel than many high-durability options. However, if you have a history of arm issues, you might consider using it in a hybrid setup with a softer multifilament string to reduce overall stiffness.

The round profile provides a very predictable and consistent response on every shot. Unlike shaped or textured strings that are designed to grab the ball for extra spin, the round shape focuses on a clean, smooth feel that helps with touch and directional control.

Flash is an excellent choice for hybrid setups because its round profile and durability make it a reliable 'main' string. It pairs well with softer crosses, allowing you to balance the longevity of a co-poly with the comfort and power of a different string type.

Thinner gauges like 17 or 18 will offer more feel and spin potential but will break faster. Thicker gauges like 15L or 16 provide maximum durability and a slightly stiffer response, making them the better choice if you are a frequent string breaker.

Like most co-poly strings, Flash will experience some tension loss over time. However, it is designed to maintain its playability characteristics well throughout its lifespan, meaning it won't feel drastically different as it ages compared to some other polyester options.
