I've done maybe 15 butts over the last 2 years since I've found this site and bought my smoker. I've always wrapped in foil at 145 or so and then took it up to 205. Well the last one my wife said was a little greasy so I did one this weekend and decided to try it without wrapping in foil and it turned out AWSOME! I took it out 195 and it had AWSOME bark on it and there was hardly any fat in it when I pulled it. My wife is really picky about the fat so when I pull them I always pick out every last piece of fat, on this one there was maybe a fourth of the amount of fat as usual. Maybe it had less fat in it to begin with or maybe more of it cooked out, not sure but it was GREAT and I dont think I'll ever wrap one again. I was always a little nervous to try it without the foil but I'm sure glad I did. Heck who knows next time I might even try to rub musTURD on it before I put on my rub, even though I cant stand that stuff.
