Yup, cheap tobacco will do you in - especially cheap aros, which, as was pointed out above, are loaded with gunk. Explore some of the house blends our sponsors have. I have had pretty good experiences with the Hearth and Home line from Pipes and Cigars. Haven't smoked any of their aros, 'cause I'm not an aro guy, but they have some nice burley blends, as well as latakia blends, that are fairly inexpensive when purchased in bulk. Old Companion is a pretty good all day sort of blend.
