Well I took the BB out this weekend for it's first hang with the UCR's and ended up awaking to the sound of sliding rope followed by a gentle thud as me and my BB descended to the ground (more than once over the two nights I was out). The UCR's were made with 7/64 amsteel with 10" bury's and I made sure to back it up with a slippery half hitch. Both the half hitch and the bury pulled through and loose. I even tried wrapping the loop of the half hitch around the toggle backed up by a second have hitch with the same results halfway through the night. Any suggestions on preventing slip with the amsteel UCR?
