I experienced many tangles stacking until I figured out I had too long of a bottom lanyard. Now I make sure the top line is clipped at least a foot further up than the length of the bottom lanyard, and I tighten up the top line first. That cheater set up sounds interesting. Might have to try that some time, especially during the silver run. I wonder what happens when you have a double by yourself? I've doubled with my flyrod a few times. Lost a favorite fly that way.
