I did brisket indirectly on a gas grill with a smoke box before I got my smoker and joined here. I only counted the time that I've had the smoker in how long I've been smoking.
Also, I'm not trying to discount what anyone says, if you prefer low and slow then fine, just don't say that it can't be done in 5 hours or it won't be any good if you do it that way. With it directly on the grate for 3 hours at 250* it gets a good bark and the temp will come up to around 185* after it's been in the foil for two hours. Actually I think my last one got up to 190-195*, so if you want to leave it in until it reaches 205*, then it shouldn't take very long at all. It's a procedure that a rancher / restaurant owner told me when I bought my 1st brisket from him. That man knows more about meat and smoking than I ever will.
I'll be the first person to tell you when I don't know something, but when I DO know something from experience, it irritates me to no extent when people argue with me like I don't have a clue just because they always do it differently.
Sorry to be so long-winded, and I hope that I haven't offended anyone.
