The "I Don't Know" blend from the pottery bowl I use to to dry tobacco and over which I often pack my pipes, my version of "The Best of the Rest," in a smooth Stanwell straight bulldog 32; this "blend" has been drying for weeks and is perfectly smokeable and quite good. I'd say mostly burley and Virginia and no flavoring. I love these little Stanwell 'dogs, so I bought two, a Silkbrune and a Smooth.
