Head to head

Tecnifibre HDX Tour 16 (1.30) vs Wilson Natural Gut 16 (1.30)

HDX Tour 16 (1.30) leads on 3 of 6 measurements. The widest gap is ball bite, where HDX Tour 16 (1.30) is 22 percentile points ahead. Every figure is a testing-machine result at a fixed reference tension.

Bars are percentile against all 788 strings, and the marked side is the one that measures better — which is not always the one you want. A firmer bed is worse for your elbow and better for your control, and no measurement knows which of those you came for.

Which one wins, by problem

Each string's standing on the site's rankings, out of every measured string in the database. This is where a comparison stops being arithmetic and starts being a decision.

Swapping between them: what tension?

Bed stiffness is published at one reference tension, so the only honest conversion is to scale it. These are starting points from 52 lb, not prescriptions — the calculator takes your own tension.

Coming from HDX Tour 16 (1.30) at 52 lb

String Natural Gut 16 (1.30) at 70.0 lb 31.8 kg

Clamped — the proportional answer was 83.8 lb, outside what most frames are rated for. These two are too far apart in stiffness to match by tension alone.

Hybrid: what if you used both?

Estimated, not measured. No hybrid combination has been tested as a bed — these figures are the two strings' own lab measurements weighted by how much of the bed each one actually is. Treat them as a guide to which way a pairing moves, never as lab data.

Which goes dead first?

Estimated from tension loss, which is the only thing the database measures about ageing. This is when the bed stops playing the way you strung it — not when the string breaks.
