What's the story on the Mag Switch? I've heard nothing but horror stories about them flaking. If you were able to get a pair, would you wear them or just display them? What's underneath the magnesium paint? Is it possible that when the paint does start to flake to just strip the entire frame of the paint? Does sweating really accelerate the corrosion that badly? What about skin oils? Would that accelerate the corrosion as well?
