How it ranks against all 789 strings

Stiffness 76 lb/in · 0th pct

Stiffer than 0% of strings tested — exceptionally soft and forgiving.

Tension loss 10 % · 0th pct

Sheds more tension than 0% of strings tested — outstanding tension maintenance.

Energy return 97 % · 99th pct

Livelier than 99% of strings tested — huge free power off the string bed.

Spin potential 2.3 · 3rd pct

More spin potential than 3% of strings tested — minimal spin generation.

Ball bite 0.442 COF · 51st pct

Grips the ball harder than 51% of strings tested.

Snapback 0.191 COF · 97th pct

More string-on-string friction than 97% of strings tested — notches badly and stays put.

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.
