Dynamite Soft 17

Nylon/Zyex Gauge 17 1.21 mm In production

Lab measurements for Ashaway Dynamite Soft 17, 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

120lb/in

lower = softer, kinder on the arm

Tension loss

28%

lower = stays where you strung it

Energy return

91%

higher = livelier, more free power

Spin potential

2.6

higher = more spin off the string bed

Ball bite

0.527COF

higher = grabs the ball harder

Snapback

0.204COF

lower = strings slide and snap back

How it ranks against all 789 strings

Stiffness 120 lb/in · 3rd pct

Stiffer than 3% of strings tested — exceptionally soft and forgiving.

Tension loss 28 % · 43rd pct

Sheds more tension than 43% of strings tested.

Energy return 91 % · 65th pct

Livelier than 65% of strings tested.

Spin potential 2.6 · 5th pct

More spin potential than 5% of strings tested — minimal spin generation.

Ball bite 0.527 COF · 86th pct

Grips the ball harder than 86% of strings tested.

Snapback 0.204 COF · 98th pct

More string-on-string friction than 98% of strings tested — notches badly and stays put.

More from Ashaway

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.
