I like the larger gold badge with the black edging the best. Centennials are cool too. I'm not a fan of the red S badge. It looks peach colored to me and makes me think it's a fake..it's just so different.
Cathy, that's pretty interesting on the manuals. I've only just starting watching how they were different sizes, shapes and colors but haven't paid close enough attention to gather all the details you have yet.
