"Dino Bones" have alot more fat on them than pork ribs, so there is no need to foil them. I do them quit often and they are very good.
My suggestion: Smoke at 225*-250*. Treat like pork ribs (rub w/ mustard and favorite rub). Place bone down for 1.5 hrs, then spritz w/ favorite mop/spritz. Do this then every hr until done. Look for the "pull back" from the bones. I like my bones medium, so a small rack will take around 3-3.5 hrs, longer for larger racks. Again, the beef ribs have lots of fat in the meat so there is no reason to foil.
