RaineDav, that event is run by guys who knew Walt Goode on a first name basis! Those guys still make wing fillets out of leather. Compared to just cutting a slit for an EZ hinge, then covering the entire prehinged assembly in one shot with iron on, all these other techniques represent to me are ways to slow down airplane production and take time away from flying. I like to seek out methods that are the lightest, simplest, quickest, and if at all possible, the neatest to look at. Most importantly, the end result has to be something that you can live with weekend after weekend at the field with the lowest maintenance. Laminating a fabric hinge in between two layers of 1/16 balsa can't gain you one iota of anything, really, except for the time it takes to build the model, and possibly a heavier tail VS using 1/8" balsa and EZ hinges, which has been tested [so far as we know] up to 150 mph on some 1/2A planes.
