The advantages of the metelious rap hangers. Super discrete, super burly, cheaper than Fixe ring anchors, never wear out. Same rope bearing surface of 5/16th quick link. Disadvantages, not as user friendly @ hanging belays for # of biners in hanger and still be able to fit the rope in there but still totally manageable for anyone who is not a complete sport weinie. Slightly more wear on the rope when loweing but still negligable. pulls slightly harder but that keeps you warm. I do prefer the Fixe single rings painted grey for medium use discreteness. Quick links or metelious rap hangers for high use. the quick links you can replace. the metelious rap hangers never wear out? Anyone seen one wear through?
