ATP Poly Power Pro 16L

Polyester Gauge 16L 1.27 mm In production

Lab measurements for Pacific ATP Poly Power Pro 16L, 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

194lb/in

lower = softer, kinder on the arm

Tension loss

51%

lower = stays where you strung it

Energy return

84%

higher = livelier, more free power

Spin potential

5.0

higher = more spin off the string bed

Ball bite

0.461COF

higher = grabs the ball harder

Snapback

0.092COF

lower = strings slide and snap back

How it ranks against all 789 strings

Stiffness 194 lb/in · 62nd pct

Stiffer than 62% of strings tested.

Tension loss 51 % · 90th pct

Sheds more tension than 90% of strings tested — goes dead fast, expect frequent restringing.

Energy return 84 % · 12th pct

Livelier than 12% of strings tested.

Spin potential 5.0 · 57th pct

More spin potential than 57% of strings tested.

Ball bite 0.461 COF · 62nd pct

Grips the ball harder than 62% of strings tested.

Snapback 0.092 COF · 50th pct

More string-on-string friction than 50% 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.
