Like Recoil 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 Recoil 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
~31hours
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 8 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.
Elongation under load
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".
Bed stiffness against tension · Fast swing
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 45 lb/in that does not come from tension at all, and gains roughly 2.5 lb/in for every extra pound you string it at.
What that means
Stringing Recoil 16 at 30 lb gives a bed of about 120 lb/in; at 70 lb it is about 221 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
34.0ms
How long the ball stays on the string bed. Longer dwell is the physical basis of what players call hold or pocketing.
Bed deflection
33.0mm
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
35lb
The highest force perpendicular to the string bed during impact. The spike the frame and the arm actually receive.
Tension at impact
39.1lb
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
6.2lb
Tension lost simply from being strung and left alone, before a ball is hit.
Loss: bedding in
5.5lb
Tension lost while the bed settles over its first impacts.
Loss: impact
0.4lb
Tension lost to the impact itself. Frequently negative, because a bed often gains tension across an impact rather than losing it.
Loss: total
12.1lb
The three losses above added together, in pounds.

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.
