Well I definitely like VG.
So much, in fact, that most of the time, I add a drop of G to a ml., or combine VG and PG, or both.
I would definitely vote for menthols and tobaccos. Without a good variety of tobaccos(including menthols), my opinion is such that many smokers will not even try
vaping to begin with. I'm talking about smokers, not expert vapers. That is my personal experience; I mean I went through that myself.
I tried
vaping because a local store happened to have tobacco and menthol. Had the clerk said something like "Sorry, ecigs only come in pistachio or spinach or something strange", I would have never even tried vaping. Smokers buy their analogs precisely because the clerk has their flavor, and that was key to allowing me to try ecigs. So I definitely vote for as many analog tobaccos, as well as some menthols. I do now ('after' I switched to ecigs) very much like other flavors, but I still vape analog flavors and menthol most of the time.
By the way, what do you mean after vapefest you found out you're allergic, and are you allergic to PG or are you allergic to too much PG? I used to use lots and lots of PG, and noticed a slight reaction. It went away as soon as I didn't use so much PG, combined with a reduction in shampoo, and deodorant. I did use to use lots and lots of deodorant, which was unnecessary, as well as superfluous amounts of shampoo.
