Graeme,
If I was in your situation I'd be looking at this new prop from Duc. Looks like
they've thought about the design and have done a fair bit of computer analysis
on it. It claims to have a 'Constant Speed' effect for a fixed, ground adjustable
prop. Sounds too good to be true maybe but worth a look:

That looks like an interesting development but the spec sheet looks like a minimum
diameter of 1660mm for the 80hp which is larger than the current LAA monowheel
guidance of 1625mm.
