seems to be this could be a much cooler/more interesting/more useful thread if people would post the brand/type of the BEST chain they've ever used, for whatever application. i've only ever used stock chains, but lately people like mopedshop.com and 1977mopeds.com are selling racing chains, and i keep seeing them and wondering how much difference it would make . . . so, you out there with race chains: what difference does it make? is it worth it for street use?
