Whoopee slipping

This is a well-chewed bone...for our purposes, hammock suspensions are where the rubber meets the road, and the only questions of interest to me are these: Has an Amsteel hammock suspension ever failed in use? If so, how and why?

After seeing Gargoyle continue to hang successfully on the dynamee, I continue to be amazed. Other than this thread, I have never heard of a whoopie failing with amsteel. I cannot imagine slippage, as physics seem to negate the possibility if the whoopie is properly made and installed.

I am making stuff with amsteel 7/64 and 1.75 zing it right and left now, and while not scientific, I think these products are amazingly capable for the stuff we do. I have become a real fan of the soft shackle biner.
I have no concerns.

To me, it's mostly about comparing apples to apples. Given Samson's statement that their ratings include the splice, then I consider a 5:1 on their rating to equal (more or less) a 10:1 margin when using whoopie slings. I'd be good to go with that (5:1 on Samson's ratings).

I think it's the old caver in me that understands the catastrophe when rigging fails. I know of several deaths in cave repelling. Rigging for human safety is nothing to cut corners on using "common knowledge/sense" (and you know what they say about "common knowledge/sense").

Whoopie slings are new to me. I enjoy thinking through the construction and use of them with everyone here. On some forums, folks would already be calling each other's mothers name. Not here!
