Like Explosive 16, but…

Almost nobody looks a string up out of curiosity. You are here because something about your current setup is wrong. Each list below keeps the rest of this string's profile as close as it can while moving decisively on the one thing you picked, so these are swaps rather than merely different strings.

What Explosive 16 is actually good for

Its standing on each of the site's rankings, out of every measured string in the database. Same arithmetic as the finder, not a separate opinion.

How long it lasts, and how far it stretches

Playable life

~22hours

Estimated from tension loss, on a scale running from 40 hours for the best-holding strings in the database down to 10 for the worst. At four hours a week that is about 6 weeks.

Estimated, not measured. This estimates when the bed goes dead, not when the string snaps. If you break strings before you notice them going dull, you are a breaker, and thickness and material matter far more to you than tension hold does.

This stringDatabase median

How far the string stretches when tensioned to a given load. A string that elongates more absorbs more of the impact itself and feels softer; one that barely moves passes more of it on to the frame and the arm.

Measured at every tension and swing speed

The figures at the top of this page come from one test condition: 51 lb at fast swing speed. There are nine in total, and all of them are below. Tension moves the bed more than the choice between two similar strings does, so this is the table that actually answers "what will it feel like for me".

Measured at 3 tensionsFitted response

Measured at three tensions, with the fitted response drawn across the whole stringable range. The line does not pass through the origin: this bed carries about 150 lb/in that does not come from tension at all, and gains roughly 1.6 lb/in for every extra pound you string it at.

What that means

Stringing Explosive 16 at 30 lb gives a bed of about 198 lb/in; at 70 lb it is about 262 lb/in. That range is wider than the gap between most pairs of strings on this site, which is the single most useful thing this page can tell you.

What else the machine recorded

Further measurements from the same test, given at the reference condition of 51 lb, fast swing.

Dwell time

33.8ms

How long the ball stays on the string bed. Longer dwell is the physical basis of what players call hold or pocketing.

Bed deflection

30.3mm

How far the string bed moves at impact. More deflection means the bed is doing more of the work of stopping the ball.

Peak force

32lb

The highest force perpendicular to the string bed during impact. The spike the frame and the arm actually receive.

Tension at impact

33.0lb

What the bed is actually pulled to by the time the ball arrives, after it has settled. Always lower than the tension it was strung at.

Loss: settling

6.7lb

Tension lost simply from being strung and left alone, before a ball is hit.

Loss: bedding in

11.1lb

Tension lost while the bed settles over its first impacts.

Loss: impact

0.5lb

Tension lost to the impact itself. Frequently negative, because a bed often gains tension across an impact rather than losing it.

Loss: total

18.1lb

The three losses above added together, in pounds.

More from Dunlop

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.

String friction · COF

String-on-string friction. Lower lets the mains slide and snap back into place after impact.
