You know, It had never occurred to me. I hate the yellow CANON on my T-70, and might just tape it over it before my trip.
My 6x6s, on the other hand, have always been more duct tape than metal (that's an exageration). My current one, a Pentacon Six, has a homebrew waist level finder shade (made out of black FOAMIES and duck tape). It also sports a nifty yellow masking tape filler on it's lens cap, so it will hold tightly to the metal lens hood.
My old TLR had wires stiches and duck tape on the leather case, and a foamie/duck tape (homebrew) square lens hood.
So I guess I'm with you on the "tapers" team.
