I too have always used EZ connectors (listed above/hex/brass). My father-in-law put my first plane together this way. All that to say I have used EZ connectors for no good reason other than I didn't know any better. I can report after 2 years of flying profiles with throws in the 50 degree range (this inludes full throttle snaps, climbing flat spins and waterfalls) I have yet to have a failer (makes me nervous to say that). I fly them as hard as I can and have had success. I do add a drop of CA to locking screw.
