Just decided I would make some. Last time I smoked it, I had bad issues with the casing. Never happened before. Hoping it was old, bad hog casing. But just to hedge my bets I did some in cellulose casings too. The natural casing need to air dry about 2 hours, (you use what you got) not sure it will help in the cellulose casing, but cant hurt. Supposed to smoke 3 hours at 150°, then raise temperature to 170°. I cant get that low on the Pro, I can get to about 175° with some fiddling, so will probably just try that and pull at 140° to 150°, and hope it get some smoke on it.
