Well, Frosty, as I understand the purpose of the regulator and needle valve: Set the regulator at the maximum pressure you expect to need. (as you've said in the past, no-one needs even 30 pounds with these forges) Then adjust needle valve from 0 to whatever pressure meets your needs. Yes?
Oh, and I've ALWAYS got popcorn. It's always first on the shopping list. I just don't eat it at the same time as drinking apple cider. Massive amounts of undesirable/unwanted flatulence abound!
