My experience is with O rings of the same inside diameter as the width of the webbing being used. I am not aware of slippage when under consistent load with 1 inch tubular nylon.
Bouncing with thinner webbings and especially the 'looser fit' provided by D Rings it certainly may be possible.
In any case it is easy to route the webbing end back through both rings yet again and tuck it under
the rings rather than tie a loop. Its cleaner and lifts the metal, no matter how smooth, off the raft.
The rings will not tear up webbing like a cam.
The first caveat here would be varying tube pressure and attention to detail.
A second caveat is that one can really ratchet down the rings. Too tight isn't a good thing.
A simple test for 'under reasonable load' would be to secure the double ring side to a 10 foot high tree limb and have the main webbing foot loops under your body load. Be sure to felt marker the web at the ring and jump in the loops that are only a couple feet off the ground. Think of this as a pre-test for hammock security.
If it slips think about a webbing that would hold. Such as a thicker one but not necessarily stiffer.
Even go ahead and do the route through the rings agin thingy.
Failing that I'm subject to eating one medium sized crow.
Don't try this at home with a nylon webbing that has been in the sun on river floats since 1995 and abraded by a cam. Even if only a foot off the ground.
