I've been using the smoker for about a year. Love it, but I'm still a newb. Overnight last night I did brisket for the 2nd time. I was surprised both times about how quickly they were done. The first full brisket was 13 lbs and this one was 15 lbs, both before trimming fat. Both were done in about 10 hours with the temp in the WSM around 230-250 the whole time. I would have expected it to take a lot longer.
