I use anchor hitches to attach my lanyard snaps and my biners that go on my climbing lines and splits tails. I leave a 2" tail. I probably should leave more but I don't like the extra rope dangling around, and have NEVER, not once, seen an anchor hitch creep or act up once it is dressed and loaded with weight to cinch it up. My current lanyard is 5 years old and tied to a steel snap with an anchor hitch and has not changed position since the day I cinched it up 5 years ago.
