My first time smoking prime rib - 4 bone 7.7 lbs. Used a combination of cherry wood and pecan wood. Got a nice light smokey flavor. Turned out to be the most tender prime rib I've ever had.. so far rubbed down with olive oil, fresh ground s+p, and some other spices. hour in 1/2 way there... done, and rested JUICY!!!!! over head view All said and done it was great! Will do again for sure.
