>an upright should provide higher pedaling efficiency than a velo, since the only advantage a velo has over a bike is aerodynamics.
Okay but you cannot make uprights more aerodynamic comfortably so you NEED to use a more aerodynamic type of bicycle, so your point is moot.
>recumbents have their own host of issues, significantly worse handling, much worse ride quality with smaller wheels to absorb road impacts etc.
And all of those you just made up, ride a good recumbent.
