I burned hickory,cherry and apple pellets for these. I always pull the membrane off too. These were put on at 230 degrees for 3 hours then foiled tight with a little butter and more rub for another 45 minutes at 260 degrees. Then about another 30 minutes out of the foil. Outside temps were in the low 50's and breezy. The ribs from Wally are enhanced with saline so I usually don't add too much to them.
