Catto Prop Experience?

[grassroots]

Anybody using athree-blade Catto ontheir 180hp S-1S? With my current Sensenich 76x59, full power straight and levelsees 160mph IAS @ 2900 rpm. Stabilized full power flight at 3000 rpm sees 170 mph. Climb at 100mph sees 2500 rpm.Craigmakes a 56 and 58 pitch prop (72 dia)for the S-1S and I'mtrying to figure out which would work best, without losing high-end speed or low-end thrust compared to what I'm running now. Just looking forsome comparison data for anyone running his prop on their 180 hp unmodded S-1S.Already looked over search results. Thanks
