My AMGA comment was more to illustrate the sheer volume of use the cordolette has seen, (and taken big falls) yet one doesn't hear about anchors failing all over the world because of it. It was not suggesting an AMGA endorsement, simply that it has seen heavy use w/o consequence.
Perhaps there is a stronger method of linking pieces together. However there is something to be said for a very simple and clean power point that can be clipped and cleaned quickly, and w/o error.
Of course it is important to be open to new data, as you suggest.
