Have been wanting to smoke some different kinds of meats like brisket, shoulder, etc. but don't have a dedicated smoker. I do have a nice natural gas Weber Summit Gold that's about 10 years old now but still in excellent condition. Eventually I may get a nice dedicated smoker like the Smokin' It or similar, but for now, it sure would be nice to be able to use my expensive grill to smoke as well! My cooking grate size is probably 36" X 18" or so, and I probably wouldn't be getting above 250 degrees or so for the brisket or shoulder. What would you guys recommend, the 18" tube smoker, or the 5" X 8" pellet smoker? From what I read, it looks like the pellet smoker releases smoke longer, which may be needed on 12 hr. or more cooks. Is this because it holds more pellets or just releases the smoke slower? Also, if I go with this model, would you recommend the sawdust or pellets? Thanks!
