I think I'm on the opposite end of the specturm.  I have pulled off all but one of the decals off of my Bell Northstar and Bell Merlin II - useless weight. Only left the model name decal on one side of each boat in case I ever want to sell one.  Otherwise, I just tie gear in with a few strings when needed.

only thing I've added is a Tugeye on the Merlin, so I could lock the canoe up with a thru-the-hull cable.  still need to do that to the Northstar, but that'l be it for modifications

whitewater boats are a different animal, of course, and are rigged with bag cages, D-ring patches, knee pads (and thigh straps on one boat)
