Favorite has to be my Birthyear Dunnie, gifted to me by a friend....and a great smoker to boot. This one sees nothing but VA.
Most recent, and maybe my best smoker, although a short (20-30 min) smoker, is this Paulo Becker 4-Diamonds. Runs a close 2nd to the Dunnie as my favorite. Again ... VA blends.
Favorites are hard. I've got a few that are favorites for a particular blend or type of tobacco, and dedicated as such. (shrug)
