I've had Flexofold, Maxprop and Martec. I would definitely stay away from Martec. I don't like non-geared folding props. If one blade doesn't open you can do a lot of damage, including bending the shaft. I've done that with a Martec, Maxprop is a very good prop but very expensive. I like my now Flexofold and it seems to have the best review. I have no experience with Gori, but it doesn't rate as well as the Flexifold.
