In order of ascending power: wind ratios:
Aero bike
Tandem
High racer recumbent
Low racer recumbent
Velomobile
My choice for 200+ miles is high racer. I'd get a velomobile, but they are pricey and hard to transport.
I understand many people are in the " I'd rather be dead than be seen on a bent" category; if that's you then of course ignore.
