You'd think the AFC red and blue would perform better. Could be the stock's a bit stiff - smooth cards have a tendency to be stiffer.
I'm a fan of the Steamboats. Light, just the right stiffness, and Magic Finish gives them good glide.
If you want something thicker to work with, the black/silver Erdnase Acorn Backs from CARC in Ivory are also coated with Magic Finish. The other Ivory CARC decks are all standard finish, to my knowledge.
