I don't think less known pipe brands are due to customer recalcitrance. I think it is a matter of volume, distribution and marketing. I'm not a business consultant, but I play one in my head. The brands we know well are mostly the brands that work hard at making that happen. A particular brand many not target the U.S. market that hard. I like my two Luciano a lot, a billiard and an author, but I don't hear much about them, and I have a few other brands that are obscure.
