Dyreex Black Edge Whirl String Test February 22, 2016 05:23

This time it's the turn of the Dyreex Black Edge Whirl to undergo mechanical testing by Eng. Gabriele Medri.

In this case, a twisted string with a gauge of 1.27, also available in 1.25mm and 1.30mm gauges.

A string created for spin and baseline pressure lovers, with very good tension retention.

Below is Eng. Medri's test with his conclusions:

The DYREEX BLACK EDGE TWIRL 1.27mm belongs to that generation of shaped, twisted strings aimed at all players who want to benefit from the increased elasticity provided by the twisted string. In this case, the string still maintains a particularly high consistency and stiffness, promising very taut stringbeds. Very powerful, dedicated to spin due to the undisputed "snap-back" action of the new string and certainly also after break-in due to its helical geometry. Tension stability is decent, although an appreciable drop in tension is to be expected after the first 2 hours of play, which might suggest an initial pre-stretch of 1-1.5% resulting in a tension drop of 1-1.5kg. Good static tension retention confirms the quality of the material. Durability is normal, which, like all monofilaments with distinctly competitive and performance characteristics, is around 9 hours of play with a marked but not radical stiffening.

A STRING WITH A COMPETITIVE AND "AGGRESSIVE" SPIRIT. DEDICATED TO THOSE WHO PREFER SEEKING SPIN AND UNRELENTING BASELINE PRESSURE.
