They definitely sound like fickle plates indeed. I'm in the process of reading more about modern Lippmann stuff, but once I get it all straight in my head, I might be willing to split an order with you. However, one more person would sweeten the deal, as 10 would be just enough probably.
Furthermore, what plans do you have for holding the film? Any idea how thick the PFG-03c plates are? I actually emailed laserreflections but they've yet to get back to me with the answer.
