After smoking for a while I often foil beef roasts with some onion slices; adds a nice flavor. Otherwise, FLbentRider has several great beef recipes up his sleeves.
I will season my roast with some Big Poppas Double Secret and some garlic pepper, and cook at 225 till internal temp of 165. Then I put it in an aluminum roasting pan with an onion, a couple bell peppers, some diced garlic, and even some jalapenos. Add some Worcestershire sauce and a bottle of beer, cover with foil and continue cooking at 275 till internal temp of between 195 and 200. I then shred the beef and serve on substantial rolls with either provolone or pepper jack cheese. My co-workers love when I make this, because they know I am going to be bringing leftovers into the office! The finished product below didn't have the good cheese, but all afterward did!
Rub roast with Salt, Pepper, Garlic powder, insert slivers of garlic.
I ran it on "smoke" (170-180F) on the MAK for 2 hours and then to 205F - The lower the temp,IMHO, the more even the cook.
Your target pull temp depends on your preferred final temp. We like Rare, so I pull it at 120F. (you can't un-cook it later!)
I then Foil, Towel, Cooler until 30 minutes before serving time. At that time, put it in an pre-heated MAK or house oven at 500F (or as close as you can get) for 10 minutes. Pull and rest 20 minutes, carve and serve. I can dig up some pics if you like.
If you are more of a medium crowd, adjust the first pull temp to 130F - I get about a 5 degree rise in IT from the 10 minute high-heat blast.
The ten minutes is for an average size rib roast, 5 to 9lbs. any larger and I would probably cut it in half.
