I like the plastic pin hinges. You can remove the pins if ever necessary, and there is less resistance to the control surface (though I'm not sure how much that really matters). CA hinges are very quick and easy to install and I have not had one fail yet, either. If one does fail, though, you have to cut them all to make a repair. Plastic hinges use a different glue that takes longer to bond and install, but gives you more time to get them right.
