Tension loss 15 % · 4th pct

Sheds more tension than 4% of strings tested — outstanding tension maintenance.

Energy return 94 % · 92nd pct

Livelier than 92% of strings tested — huge free power off the string bed.

Spin potential 5.5 · 69th pct

More spin potential than 69% of strings tested.

Ball bite 0.459 COF · 61st pct

Grips the ball harder than 61% of strings tested.

More from Head

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.
