I'm not knocking the job you did Dave, and one should replace the wires way before the extra stiffness becomes a problem, but time has shown that a properly squished nico will never let the wire slip out. The failure point is almost always on the eye side of the nico. But double nico sure FEELS safer! (and its easier to cover the cut end of the wire with a second one instead of getting the first one perfectly placed with no meathooks hanging out...)
