That makes perfect sense, but if you don't have some foil handy and plan on cooking a butt or brisket at 350*...you better really like a HARD, DARK BARK...a lot.
I won't bet on what it'll taste like, either.
I've tasted a couple of bites before, once at a local bbq joint that's since closed down...
...another on a HH cook OF MY OWN, where the bark actually ended up tasting "burnt". I was cooking on a cheap offset and had some 325*+ spikes, and after the cook wrote in my bbq journal to never again try to cook over 275* again without wrapping.
What Kevin said is right and makes perfect sense to me though....just stick to a good HH method and wrap in foil once the bark is right and the meat is smoked.
The surface can and will eventually get hot, especially if using the bottom grate. To tell the truth, I don't know what that other rub ingredients might get bitter just as bad as burnt sugar can. I don't put sugar on steaks, and I know what the flames can do there. The area outside of the pan on the bottom rack is not that far from the fire, and even cooking on the top grate isn't like cooking in an oven.
All that is over-stating the obvious, as I'm prone to do... but maybe it might discourage someone from experiencing a less than stellar cooking experience, too.
