Took a bit of a hybrid approach on this today. One low and slow recipe called for 3 - 3 1/2 hours at 200 -225 another weeknight tenderloin recipe called for 40 mins at 375. I tried 75 minutes at smoke on my L'il Tex and then finished it off for 20 mins at 350. Turned out with a great smokey flavor and still very, very moist. Deee-lish!
