CocoNara's or Belgian Natural discs from South Smoke are my favorite, and the best.
Exoticas are just a hassle.
Golden QL Coals from h-s and Nazar are justa s good as Nat. Coals, and easier to use and have the best heat management, but just cost too damn much. And after the foil is open for a week you have to light them on a stove outside, if you have a portable, cause the powder stuff that ignites goes dead in the air.
