I'd be willing to bet that all the various American Spirit varieties (regular, Organic, Perique) share a strong family resemblance---as middle-of-the-road but tasty American-style tobacco blends. Looking for an NET that has a good cigarette-like flavor profile? American Spirit fills the bill better than any other tobacco I can think of (or any other that I've extracted).
In addition, I imagine that most extracts/juices made from a given tobacco in the American Spirit brand line will taste remarkably similar, regardless of who extracts it. My American Spirit Organic extract is probably nearly identical to Clay's retail Organic Spirit at N-E-T.com, and both are probably not too far in flavor from boomer's 'regular' American Spirit extract.
