Hay guys im pretty new with my 22.5in wsm and im going to be doing my 2nd cook on it tonight and its an 8lb butt. Its going to be cold here in wisconsin { around 7 degrees with 4mph wind } tonight and I was thinking about putting the butt on around 2am and was wondering with it being this cold will a full ring of kingsford get me through the cook or will i have to add some charcoal ? Im guessing 9-11 hour cook? Im running a digiq DX2 by the way if that helps. Any info would be great and thank you in advance.
