OGL goes copper most quickly. I think in the long run I sell more straight OGL than I do packs. It's hard to tell because I do these buy everything pushes at the begining.
Only about 2/3 of my volunteers have bought. When the rest buy, it should pop the rest on top. I haven't actually announce the release on a prodominantly OGL forum yet, except to exisitng customers. Thanks for the reminder.
