How it ranks against all 789 strings

Spin potential 7.3 · 93rd pct

More spin potential than 93% of strings tested — elite spin generation.

Ball bite 0.521 COF · 84th pct

Grips the ball harder than 84% of strings tested.

Snapback 0.071 COF · 6th pct

More string-on-string friction than 6% of strings tested — slides and snaps back freely.

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.
