Hey, kimert! Sorry I didn't get back to you but I travel for my job and stayed at a couple of places with limited internet access. At any rate you got the info you wanted.
I knew you would show up sooner or later, so I wasn't worried

Milo, from the two decks of pre USPC Kems I have, I have not noticed any talc. If there is Im sure its there as you said to combat moisture.
