I don't think that this is an issue you'd consistently catch by inspection, but rather one that could reduce the load at which the knot fails. It would not necessarily be something that occurs gradually (although it certainly could)Yes, that clears up your point. Thank you. I pull the tag end tight, then pull the loop tight. I can see your point on flimsy strapping or webbing that is small. I have not seen any issues with this connection on the stiff and thick material of my linemans loop and I examine frequently. But maybe I should go back to the figure eight.
I'd considered anchor hitch, buntline, estar hitch as possible replacements.
