Bounding might be a possibility.

Mike is saying that they can find one suitible for their specialization, but
it is nowhere near optimal for flapping cruise because they are unable to
retract the wing significantly during the upstroke. That implies an
unavoidable, relatively low thrust coefficient in forward flight.
---------------- Actually, I get that on an "intertaxic" comparison basis. I
meant I don't understand why a gait within the taxa that is less
energy-intensive than "forward hovering" is not kinematically feasible. He was
speaking intra-specifically, right? If he was, then I guess you just told me
again, and I'll just have to wait for comprehension. Maybe I will get some for
