Charlie's Pride most likely uses their own proprietary mix of spices. So unless you can identify the spice flavors you like it'll be difficult to duplicate. You can definitely smoke just about whatever cut you like in a Cookshack. You could start with the prime rib forum; lots of good ideas there and the process would be the same. Your end product will also depend on quality of meat you use. Prime beef and a long smoke at around 200 degrees should give you tasty results. If you want medium rare the meat temp would be between 130 and 140; might want to start with the lower end of that range. When the meat is cooked to temp just cool it and refrigerate completely before slicing for the deli cut.
