I am going to be smoking my first pork butt on my 009 this weekend. I have read many of the archives and suggestions here and most people seem to be smoking butt's 7lbs and higher. My Pork butt weighs just under 4 lbs. I am just trying to figure out approximate smoking time for this. I have read on the forum to estimate 2 hours per pound. Is that correct? Any other suggestion? Thanks!!!
