Any help would do! I have an igrill2 I am getting temps from.
Hey Nate Sorry that I am late in seeing your post. I figure a minimum of 2 hours per pound for butts, (Never foil a butt, myself), and I've had a few butts go over 2 hours per pound.
Hope that yours turned out good.
I don't have experience with propane and so can't offer any advice on that. There is a "propane page" on the site where you might find some answers.
