Two stems is more aero than one, I don't think so
That probably explains why Cervelo didn't beat a path to your door to recruit you to design their new bikes. I can think of at least a couple of ways the bullmoose design might lead to less drag from the bar/stem assembly, but that's not even the main reason why they did it. As with F1 cars and fighter jets, much of the work of the bit which hits the air first is shaping the flow onto the bits which follow after.
That's not really the worst angle though is it...
I give you this fugly fucking mess..
