My favorite clevis is the Sullivan Steel with the little metal clip for security. On non critical things like rudder or nosewheel, I like plastic. In fact, the plastic is nice because the clevis will usually break before the gears in your servo strip. I've never had an EZ connector fail, but I only use them on non critical surfaces. Another neat gizmo for nose gears or rudder steering, is the servo saver. Basically your control rod just floats in an easy connector and is held in place by a spring then a small wheel collar on each side. Great idea.
