Catto
As a Catto prop fan I recommend contacting the team directly and discussing your mission and performance needs directly with them. Fixed pitch composite props are a fantastic choice, but you must decide what performance envelope is most important to you. Climb, cruise, or a combo between the two. I enjoyed a Catto three blade that was optimized for max hp cruise at 8500 feet, and with it running so smooth it was easy to enjoy it at WOT, 2700 RPM on my O-320.
Consider:
Craig Catto will tell you that a fixed pitch prop optimized for your mission will give you the best possible performance in that specific operating envelope.
I will say most of us do not exercise the discipline to achieve the maximum performance takeoff numbers, so compromises with any prop are acceptable.
It would be valuable for you to hear what climb performance numbers are achieved with a prop optimized for cruise performance and vice versa.
In the end it is going to fly and look amazing. I recommend nickel leading edges, they will protect your investment even if you don?t fly in the rain. The prop will be simple to own and maintain, which is a huge plus. They are light weight, so CG considerations should be thought out. Adding a heavy crush plate is an option, but why add more weight than you must?
