True; one man's "strange" is another man's "this is great!". Pursuing this thread: Those of you who have such dual ring/dual cog setups: how often do you shift, and when? I know that, with a flip flop and even a Dingle -- all my fixies have either a cog on each side or a Dingle -- I often, when faced with a climb or wind that is uncomfortable, think of the hassle of loosening the nut or bolt, moving the chain, etc., and say, "forget it" and just get off and walk. QR axles would certainly help. I'm curious how others use their multiple fixed gears.
