Not going to lie, I do see where you're coming from with this. Not necessarily with such vitriol (perhaps I've not worked on
enough of them to hate 'em), but when I have, the Duopar has always been a distinct letdown from the hype associated with them.
Full disclosure: I'm biased. Where I live, there's no reason to wrap that much chain. Even a Jubilee is overkill around here
