There is much more to it than just thickness. When I was cleaning out Cardamation and talking to the owners, they talked about the problems they had when the last mill shut down punched card stock, and the best solution they came up with just did not work well. The stock is very much a specialty item, due to its strict specifications. The mills treated is so special that the workers making the stuff were paid by how much usable stock they produced, much to the dislike of the unions. Because of this, the mills and unions basically said that no amount of money would restart the lines. -- Will
