Thanks for the input guys, I'm going to stick with the Mazda rings.

I probably could have reused those rings; they still looked & fit like brand new... But my general rule of thumb on rebuilding anything is if it's a soft/rubbery part, chuck & replace it. That plus I may have nicked them while removing for cleaning the rotors/metal rings & springs, or may have exposed them to cleaning solvent during the process.
