I've started using one of the Z bend tools that has a pin on the head to let you get the bend in the almost perfect position.
As far as the EZ connectors, I bought a couple bags of cup point set screws in 2-56 and 3-48 sizes some years ago. with a little bit of locktite, the cup point actually lightly cuts into the wire, making the juncture much more secure. I haven't had one let go since I started replacing the regular screws these things use.
