So, I've decided to take the plunge and build a vertical smoker. Is there any general consensus on what general style has the most even temperature profile throughout the cooking chamber? From reading of posts on this forum and others I haven't found any. I'm leaning towards a vertical reverse flow like the backwoods. But, after looking at the Cookshack FEC100 and how simple it is, I wonder about just bringing the heat in the center and using a big diffuser. Any thoughts? Finally, what size would everyone want for use in their backyard? I'm thinking inside cook chamber dimensions of something like 20"x20" by 25" tall. Thanks!
