You guys can't have it both ways, if small ducted fans are "bad" then
big slow props have to be "good".

Let me clarify. I am not advocating a big slow prop. The landing gears
we have to work with are too low to the ground for that. I am advocating a slower
prop of the same diameter using the 2.85:1 psru. As Don Bates stated
we are only looking at a 2 to 3% prop efficiency loss while picking up
20 to 30 HP normally aspirated by running the engine up to 7500 RPM
or so.
