Noob here. Have done alot of grilling on a 3 burner grill, but have just purchased a Masterbuilt electric smoker to try to get the perfect brisket(or close). Doesn't look like the Masterbuilt can handle a large brisket on one shelf, is it ok to cut one down and use several shelfs?? Anyway, my user name pretty well describes the rest of my addictions! My wife complains that I probably couldn't have picked two more expensive ones.
