Vesteroid,
Look under smoked steak and you will get some ideas. Smoke your Rib Roast to about 90 to 105 degress. I do mine at CS 230 oven temp. When it hits your target temp, slice your roast into steaks 1 1/2 to 2 inches thick, and put it on the hottest grill you can make. Rotate at 2 minutes, flip at 2 minutes, grill 2 minutes, and then rotate again. (2-2-2-2 method). Move to a cooler part of the grill and grill to desired doness. I like mine at about 130 medium. Be carefull with your rub. If it has a lot of garlic or sugar it will burn on the grill at those temps. I use salt and pepper only and use a compound butter on the finished steak. Sometimes I have a hard time cutting up a $90 plus dollar roast if you know what I mean. There are a lot of other ways to do this, this is just one way that has worked for me. I have used beef ternderloin with a simular process. My wife thinks it is silly but I do my 7 hour steaks that are smoked, cooled, sliced, marinated and grilled. Pretty darn good. Less expesive that way if you can find them on sale. You can start with a Rib eye or any other steak you like and use the same general idea.
