Hello all. Newbie. First post. Just bought a '67 M20F. It has a three bladed prop and I love the looks and feel, but I'm reading a lot about the 2 bladed prop being faster, lighter, smoother, cheaper, etc... Why have the 3 blade prop? Can someone share the pros and cons of each? Is it worth converting back to a 2 blade? Is my 3 blade prop worth anything on the used market? Thanks in advance. Todd
