lower = stays where you strung it

Energy return

77%

higher = livelier, more free power

Spin potential

lower = strings slide and snap back

How it ranks against all 789 strings

Stiffness 165 lb/in · 33rd pct

Stiffer than 33% of strings tested.

Tension loss 67 % · 100th pct

Sheds more tension than 100% of strings tested — goes dead fast, expect frequent restringing.

Energy return 77 % · 1st pct

Livelier than 1% of strings tested — very muted and low-powered.

Spin potential 5.3 · 65th pct

More spin potential than 65% of strings tested.

Ball bite 0.534 COF · 88th pct

Grips the ball harder than 88% of strings tested.

Snapback 0.101 COF · 65th pct

More string-on-string friction than 65% of strings tested.

More from Poly Star

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.
