I have been splicing anything I can get my hands on. So here is the latest. Whoopie sling made from 1/8 inch amsteel (2,000 lb strength+/- ), threaded through a bit of webbing for some abrasion protection. The hook will be replaced with a rubber coated s-hook with safety latch. This thing weighs nothing, fits into my pant pocket is not bulky and doesn't dangle all over the place when I use it to climb. I think this one will be a winner for me.
