Try a smoke tube.
Love it! That's pretty much what I do, although a lot of the time I don't even spritz. Also, no sauce on the grill. I usually have some available if someone wants it, but a good seasoned and properly cooked meat shouldn't need any.
I may need to do some more research on this pellet cooker deal, you guys are pretty convincing. What am I going to replace my beer drinking time with, though?
