Catto RV-9A

I would like to hear from anyone using a Catto 2 or 3 blade prop on a 9A with an 0-320 150 HP engine. What length and pitch did you buy? Were you looking for best climb or best cruise or middle of the road? My 9A will probably be somewhere in the middle of the weight spectrum and will be running a carbureted E3D 0-320 150 HP. I am looking for a compromise of climb and cruise maybe leaning towards cruise. I haven't decided on a 2 or 3 blade yet, but have decided on a Catto prop. I am getting close to needing to order my prop from Craig and I know he will make a recommendation but just wanted to compare to what people were flying.
Thanks

I would just call Craig Catto and ask him. He has data points on all of the RV-s and what prop / pitch works best for which plane / engine combination and the mission profile you want.
