After using predator and then switching to amsteel this past month, I have the same problem!!! Especially since I did the locked brummel splices!! LolReally it's personal preference. I like the tube web I think it has the perfect amount of friction against the carabiner. Amsteel is a little bit too much slip and slide for my liking. And I know the numbers don't lie but I have a mental block against trusting my life to a 1/4" rope.
I have to agree...I to like the webbing. Maybe my days in the Marines and Army, but the military grade webbing is tough. I found some 1" wide rescue webbing that is rated for 6000#. Got over 100' of it and thinking about selling it by the foot. Got it from CMC rescue.
