Skybolt S Propeller Talk

[Topflight2]

Just about to mount a Lycoming IO-540 on my Skybolt S fuse. To test run it, I will need a propeller. I'm considering a fixed-pitch, three-bladed, wood-composite MT through Steen Aero Lab, and would like to know from others:

1) appropriate prop diameter
2) fixed pitch vs variable
3) general thoughts

What would you do differently, if you had it to do over?

Thanks!
