I messaged him about it awhile back:
"Are these the old, discontinued arrcos, or are these the new reprints of the line that includes the black/green ones?"
the response I received:
"These are the new reprints, not the old ones. (The old Arrcos are very tough to find and expensive).
These are actually the "second edition" reprints. They were printed on a different paper than the first reprint. It is the same paper used for nearly all of USPC's custom decks now.
Thanks and best regards,
Dave"
I didn't actually end up buying them, so I can't vouch for them in comparison to the old Arrcos, but that's what he had to say.
