Well, it's both. I had a special tour, for a specific purpose. They let me perforate a couple thousand feet of film in the process so that I would understand the issues. A guy who worked on them answered a lot of questions for me, so I'm working from that understanding. I'll just repeat that I think it's much more difficult than meets the eye. If one were to punch ROUND holes, and didn't mind the occasional perf hanging by a stretched bit of base, it would probably be a lot easier. I don't want to say too much more than I have.
