I went from the fancy pellet poopers back to the basics. My recent WSM smokes came out fantastic.
Not sure what Linquica has going on with the WSM, but I spend a lot less time with the WSM than I did with other types of smokers (except the electric).
Not sure what you folks are doing that are having to tend your WSM every 30 min. or so, but if you set it up with the minion method you shouldn't have to tend it more than once or twice during a smoke. I have ran up to 22 hrs. on one load of charcoal and only had to mess with my WSM 4x during the entire thing.
