Anyone ever use these types of locking crimp plug terminals ? Gotta secure everything to the max.

That's the only type of plug boot I use and the one I'm constantly recommending here. If you really want to be anal about "securing everything" do what I do and solder the plug wire's conductor to the metal connector. You'll have a electrical connection that you'll never have to worry about again. Too bad the other end at the CDI doesn't lend itself to soldering too.
As for Champion plugs, I've used, and had good luck with a Champion 811 or L82C plug. I couldn't tell any difference between it and the more commonly favored NGK.
As for a 'Low Profile' or a 'shorty' plug I've used an Autolite 2976 where frame clearance was a problem. It too performed well.
