I believe I reported recently that I went from a Martec two blade to a Flex o Fold two blade. My Westerbeke diesel engine likes to run at about 2000 RPM. The performance of the props is comparable, although the Flex o Fold seems to provide more power in reverse. Overall, I am happy with the Flex o Fold for three reasons: 1) because it folds all blades at once (smoothly, I might add), I never have a blade hanging down and don’t need to worry about aligning the shaft for racing; 2) the new prop does not do the half-open crazy vibration thing that is common with old Martecs; and 3) it was relatively easy to install (meaning that I could do it).
Hope this helps.

The reason is that a folding prop is definitely in my future, as we have a fixed 3 blade prop on the boat now. We also sail in an area where crab pots are extremely common from October through April. For that reason alone I am leaning toward a folding prop. I also saw the rather well put together article in which a test of folding and feather props was performed - the one touted on flex-o-fold's website. By the way, in exchanging emails with flex-o-fold, they are recommending a 3 blade version, so if vibration is an issue with your two blade prop, that may not apply to me. With all these considerations in mind, when it comes to a folding/feathering prop, what do you have, and why do you like it?
