Again -- and this time with my brain firing on all cylinders -- my understanding has been that the Speedster & Supremo share the same air-hardened (stronger & lighter than heat treated) steel frame. Zonally-butted and triple-butted are, for all intents and purposes, the same thing.
However, just because I don't want to fall on my sword on this, I've sent a note off to Dwan to confirm what the differences -- if any -- are. Probably won't hear back from him until late Monday or early Tuesday if past history is any gauge. After all, everyone needs their weekends and by Monday AM his Email can be pretty full, what with folks out shopping for tandems over the weekend.
Hang tight y'all. The definitive answer will be passed along.
