I got an Icetail eye and eye, was never able to get it to release nicely for descent when I wanted, really grabby in my experience. I know a lady that really likes it and she’s maybe 110 lbs geared up, so maybe me being 200lbs geared up had something to do with it. Released for ascents fine on a VT but coming down was hard. I might play with it more, there’s probably a better hitch and rope combo for it. Tenex is similar, really grabby. Strong and crazy easy to splice though.
I only tried it on a climbing system, might be nice on a positioning lanyard.
