How it ranks against all 789 strings

Stiffness 162 lb/in · 28th pct

Stiffer than 28% of strings tested.

Tension loss 53 % · 93rd pct

Sheds more tension than 93% of strings tested — goes dead fast, expect frequent restringing.

Energy return 84 % · 13th pct

Livelier than 13% of strings tested.

More from Diadem

What these numbers mean

Stiffness · lb/in

How much the string bed resists deflection. Higher plays firmer and more controlled; lower plays softer and easier on the arm.

Tension loss · %

Share of the reference tension the string sheds under a fixed test protocol. Lower means the bed stays where you strung it for longer.

Energy return · %

Share of impact energy handed back to the ball. Higher plays livelier and more powerful.

Spin potential

Ball friction divided by string-on-string friction. Higher means better bite with a cleaner snapback, so more spin.

Ball bite · COF

String-on-ball friction. Higher grabs the ball harder through the brush.

Snapback · COF

String-on-string friction. Lower lets the mains slide and snap back into place after impact.
