Full disclosure : now i haven't slept with them or anything but we did have a tug of war and I have hung from them.
Wonder if the larger diameter doesn't allow the proper ' squeeze'?
The 1/8 does have a different shape to it as well. However, I'm hoping the problem was the 9" bury. I know they're people who've made Whoopie Slings out of 1/8 and only used a 12" bury. I know the UCR needs more. How much more, I don't know.
