Catto prop

[Inverted Aussie]

Any one using a Catto 72/58 three blade on their S1S. With 180 plus hp. Looking for performance figures eg, revs at climb and speed, full throttle revs and speed cruise speed at 2500 rpm. I'm trying to decide between 56 or 58 pitch. I'm currently running a metal sensinich 76/60 full throttle is seeing 3150rpm at 180mph. I also have rv style gear. Engine is producing 190hp at 2700 rpm on the dyne before installation.
Searched forum and found some figures just seeing what else is out there.
Thanks in advance.
