I think the Thunder Bay Convers have been printed on more than one cardstock. Mine's a flexible, thin stock and the finish is fairly low-shine; it's really not bad at all. It's funny that you mention it, because I've been working with mine all evening, running the cards over the edges of my desk in between playing World of Warcraft It's softening the deck up and removing the swayback that they came with. I don't think I'll age them any further than this, though I may cut their borders off so they look nicer. I'll lose some of the background pattern, but I don't think that will bother me, and it will also get rid of some little burrs on the edges from where they weren't cut very well...
Umbrae mentions in this thread that his tea-dunk method really should only be used with cards that have the thick, USG-type finish. I'd read that thread through, paying especial attention to his posts in it. (I need to re-read it myself).
I'm going to age my RWS deck, the 1993 one sold as the "Original RWS". But I like your ideas too. It would look odd on a modern deck, in my opinion, but any with a classic look would probably work, depending on the finish you have to work with.
