irecon,
Great idea on the use of O-rings but I THINK your current implementation leaves the risk that BOTH ends of the line get caught since each end is hanging down with equipment. This leaves the remaining loop as a noose.
The O-ring needs to be away from the "stuff" that is being lanyarded and can be a weak point.

You, my friend, discovered the design flaw. I was wondering if someone would see it. I will post a pic of a solution.
However, I don't see why you think the O-ring needs to be away from the stuff that is being lanyard. In a previous design, I had the O-ring up near my neck. No good, that position is annoying and doesn't give me ready access to inspecting the O-ring.
