BHP 180    RPM 2700    Sea level speed 240

That is a very clean airplane. What kind of airplane
are we talking about
here.

I'm using 5.63" at station 1 (Ave 4.4")

Airplane frontal surface 1.05 ft^2    Cd 0.2 (I

think)

Looks like a 180 HP Long-EZ to me.

The take off
roll would be long and the climb suffers.

Vance pretty much nailed the performance.  In some ways,  this is a good
example of how the high horsepower hurts you on takeoff performance, because
you have the prop pitched for a high speed cruise.

Is there any thoughts on the Bates Propelor program as far as its ability to
optimize prop designs?

The Bates program seems to be the best there is. Kind of expensive.
