Used Pags' tri tip rub on a 3 lb Tri tip. Into prewarmed smoker set to 225. A few small oak and mesquite chips. In smoker until IT was 105. Took about 20 minutes. Then to hot gas grill and mopped with Pags suggested mop. Fire flares give a nice char. Took IT to 130 degrees. Then off grill to tented foil for about 10 minutes before slicing thin against the grain. Sprinkled with a little more rub and served.
Highly recommend you give it a try!
