Had the best success and simple, smoked yellow fin. cut into 1 1/2 in steaks equal parts brown sugar and salt and some orange zest set to smoke with Gourmet pellet mix of maple, hickory and cherry. It was on sale at costco 5 hours later beat my old smoker nice smoke and moist.
P.S.
I got the worst phone call when my wife came home, I had left for a quick errand and she saw all the smoke coming from the back yard it was the taerger 10 feet from the house.
