This is just an observation, I don't really care which terminology people use, but I find it kind of curious that people dismiss English and Balkan as recent marketing terms, and then latch on to an even newer marketing term. I know that in the halcyon days of pipe yore the term Balkan was not used, but neither was "Latakia blend" to my knowledge, only actual blend names.
Neither the English et all nor Latakia Blend terminology bothers me, as it is all a shorthand that helps the consumer quickly identify the blends they are looking for, rather than having to ferret out, either by pouring over company literature or finding some other smoker who is familiar with various brands, what a blend has in it. It does strike me that asking for a recommendation for a good "Latakia blend, oriental forward on a substrate of Virginia" is a good deal more complicated than simply asking for a good "Balkan."
