Polymaster II 16

Polyester Gauge 16 1.00 mm In production

Lab measurements for Gosen Polymaster II 16, ranked against all 789 strings in the database. Every figure below is a testing-machine result at a fixed reference tension, not a playtest opinion.

Measured values

Stiffness

172lb/in

lower = softer, kinder on the arm

Tension loss

53%

lower = stays where you strung it

Energy return

85%

higher = livelier, more free power

Spin potential

5.1

higher = more spin off the string bed

Ball bite

0.374COF

higher = grabs the ball harder

Snapback

0.074COF

lower = strings slide and snap back

How it ranks against all 789 strings

Stiffness 172 lb/in · 40th pct

Stiffer than 40% of strings tested.

Tension loss 53 % · 93rd pct

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

Energy return 85 % · 16th pct

Livelier than 16% of strings tested.

Spin potential 5.1 · 59th pct

More spin potential than 59% of strings tested.

Ball bite 0.374 COF · 10th pct

Grips the ball harder than 10% of strings tested — slick against the ball.

Snapback 0.074 COF · 11th pct

More string-on-string friction than 11% of strings tested.

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.
