There have been two blends that occupied my full attention while smoking: State Express and Constantinople. Now, both have been gone almost 30 years, Constantinople probably closer to 40 years, but neither would let you do other things while smoking them. Constantinople (C) was an over stated latakia, probably 50%, with other oriental varietals to balance and entice. Think latakia as a bass note with the orientals weaving all about the smoke, perhaps a touch of VA, but there simply was no sweetness. Nutty, but no sweetness, and an intoxicating room-note, like incense in a Russian Orthodox church. It was recommended to me by a former professor, who literally had boxes of it. I could never understand how that tobacco left the smoking scene.
State Express was remarkably different but similar in some ways. SE was predominately Turkish and orientals. Again, a light but full smoke with great aroma and flavor, and very distinctive. The sense of the smoke was broad changing tastes, pairing and then moving elsewhere.
