For most of my pipe smoking "career", burley-based English mixtures (aka American English) have been my favorite go-to blends. There are a ton of them out there, and it looks like most of the high points have been covered. Bald Headed Teacher, for instance, is an excellent example. C&D's Epiphany is even better, I think, which is only appropriate given their reputation as the best burley blenders on the market today. C&D has several other excellent examples, such as Morley's Best, Old Hollywood, Walter Franklin, etc. Boswell has Countryside, which is a pretty stellar example of this type of mixture, and the Gatlinburlier of Gatlinburg, TN has (what else?) Gatlin-burley, which was my first tobacco of this type and my all-day smoke for more than a decade. Or, you could go the cheap and easy route and mix some blending latakia with Carter Hall in a ratio of about 1:6.
