Forgot some photos: 4:30 AM (fire just lit), 10:15 AM, and 1:30 PM. Got a _beautiful_ bark and smoke ring.
Wonder if you're still watching this... I used your fuse method today to do two ~9lb shoulders on my 22" Weber. It worked really well - had a steady 225-240 burn for about five hours; after that I just kept adding charcoal (pre-lit in my chimney starter) to keep the heat up. I didn't allot enough time, though - I started the fire at 4:15 AM, put the pork on the grill at about 4:30. The larger was up to about 178 by 4:30 PM (!!); at that point I pulled the smaller off, pulled it as best I could, and we ate dinner. Don't get me wrong: it was _delicious_ and perfectly moist and tender, but could have been more broken-down for pulling. I left the larger shoulder on for another three hours or so, then took it off and broke it down as well. Next time I'll light the fuse at midnight, hit the hay and wake up at six to babysit.
All in all, though, this is a great technique. I used your rub and sauce recipes as well, and everything was a huge hit. This is my first foray into smoking on the Weber, and I can't wait to try some other things. Visions of ribs, brisket, sausage.... *droool*
