When I started vaping after 40+ years of very heavy smoking, my senses were so trashed that I really could not taste or smell anything. I started with the usual Chinese tobacco flavors (cowboy, desert, freedom...those kind of names). Those work but, one day after about a month or two, I began to taste and smell again.
BTW, the world doesn't smell like I remember it from 1970. Somebody screwed it up and I want to know who it was.
Anyway, all of those tobacco flavors suddenly tasted awful. This began what is affectionately know in my house as "the Great Tobacco Hunt of 2012". I went thru perhaps 50 samples from 7-8 different vendors but couldn'y find a good tobacco flavor. Fortunately, one of those flavors was a cherry cigar flavor and I was able to discover that I actually like to vape fruit flavors.
Today, after 4 1/2 years, I find that the best flavor is no flavor at all. I have been using unflavored for 3 years. To me, it is the closest thing to what I vaguely remember smoking to taste like.
