I prefer the flat nylon and hinge pins but when done correctly CA hinges are just fine and hold very well. If not done correctly they will pull loose, just like any type of hinge. Usually the breaking of a CA hinge is caused by trying to re-glue the hinges and the CA gets into the bending surface/area and becomes brittle. CA hinges have been used for too many years to remember without problems. Nylon and Pins are just my first choice, I just like them better, not because of a problem with the CAs.
