So I've always liked the efficiency of constant speed (who wouldn't) but I love the simplicity and lack of extra parts and weight of a fixed pitch. I've been considering the Catto or MT composite fixed pitch, but a few folks have suggested using a constant speed in my S1SS build. So the question is, which is the best option and why? I'm a heavy guy and I'm trying to keep my Pitts as light as possible. But if constant speed gives me an edge in competition, I'll consider the option.
