I like the fabric hinges, and use a nylon/polyester shirt like material. I glue it on criss cross with Sigment usually. It is a bit hard to use shrink films that way because it goes directly on to the balsa. Monocote hinges are ok too, but not as strong. I criss cross those too, overlapping 3/16" in the middle. They both give a nice free action.and look better than sewn hinges which I find that they always shift.
