The few times I've done this repair I have used cold hide glue. I figure there is still hide glue on the glue surfaces, so more hide glue would likely stick the best. It has good gap filling properties and is easy to use. I really don't see what would be better. Adhesives such as epoxy and others are only as good as your surface preparation - and there will be next to none with this repair.
