They all basically. copies of the old BALL coupling.
Which is fine on Bitumin.
OFF road. the "HYLAND" was \is the better one.
for reliability and strength. Basic. Nothing to go wrong.

ALL these other "modern ones" are basically copies of his. when you break them down.
Apart from the area the actual van takes up. that coupling has FULL 360deg rotation. in all 4 radii.

Same as everything else. The more the complexity\lightness. the more the problems and less the reliability\strength.
Keep it basic. Keep it strong. Keep it greased.
Proven for lots,,,, of yrs.

Some things ARE better. Safer.. when kept Old school.
