I'm no expert either, but I've also read that slicking the meat with oil will help the Maillard reaction, and that white sugar is more conducive to bark formation than brown sugar.

you won't taste the mustard, at all. It's just there to hold the rub.

Mike, I find that there is no advantage to cooking less than 250 for normal Q. Good bark comes from a good layer of rub, sugars help more than most all of the other stuff (unless you are using lots of fresh ground chiles). Either pre salt to draw moisture or use a liquid base like mustard or oil(s).
