Do you think there would be a significant difference between a 3-blade
feathering prop and a 2-blade folding prop? I guess my question is why would
you prefer that prop?

We need three blades to combat a vibration. The feathering prop (two or
three blade) will back more reliably. You have to be more deliberate
when backing a feathering prop. Going forward, the difference in drag
won't be noticeable.
