Catto prop specs/cost

Good info, Derek. Am I right to think that with a little less pitch, take-off rpm will be higher and climb performance a little better than, say, a 70/72?

Yes, in fact I think you will be quite pleased. What was intriguing to me with the Catto was that even though I thought it was under pitched at altitude, I never thought so on the ground. My static run-ups were spot on, 2150-2200 if i recall, and climb was good to. I could just never firewall it, unless i was REAL high. Your ability to run lean of peak (with your FI), effectively reducing full throttle HP, might just make this prop a perfect fit for you.

I think BruceH runs lean of peak a lot on his cross countries, maybe he can chime on whether or not it allows him to firewall it?

Running full throttle on a carb produces more even fuel distribution, (butterfly straight up and down) but if your under pitched you can never do that unless you're really high up....
