Your right, I wouldn't taste most of what you can. I suspect your a "super taster" and I've known one other like that. It's kind of it's own curse. I am sensitive to TH. The slightest tickle will set me off into a coughing gag response. The reason why I asked is that I'm realizing that I'm understanding where some of the regulars on this forum are coming from. From there, I can better guage where I might fit in.
I guess I'm still trying to figure out ways to organize these impressions, even if it's sort of a lost cause. Force of habit. I'm also trying to come up with an analog form, mini booklet, to keep track of this stuff and DIY flavorings, taste notes, etc. for my own use.
Impressions from others can narrow down what you decide to try for yourself, but, in the end, if you're picky about nic, you have to try it for yourself. I remember seeing posts from at least one person, who came on this thread saying they just tried nic "A" and it was the tops. Then a month later they're back saying brand "B" was the tops and they were going to dump "A" into the sewer because they couldn't stand it. Also, Wizard labs used to be he darling that everyone praised, now it's hardly mentioned. I think the competition improved more so than anything going wrong with Wizard.
I'm not that picky about nic, I've tried a number of brands and never had one that really displeased me badly when fresh. I did have one that went fishy in time, but under less than ideal storage conditions, so I don't bad mouth the vendor. I have developed preferences, especially since going to unflavored and slight menthol, but I wouldn't feel immense deprivation if I couldn't get my preferred brand.
I'm so glad I was able to take part in the blind test that Rossum sponsored. It let me try 3 brands I hadn't had before and compare my impressions to what others thought. Nude came out on top and I agreed, but not by enough of a margin that I felt compelled to dump what I already had and replace it with NN. NN is what I'd suggest to try for a newbie who comes on the forum and doesn't know where to start. Then try other brands based on what they do and don't like about NN. For anyone who thinks NN is too expensive and doesn't mind a little bit of tobacco-ish taste and TH, I recommend VT TH highly. (I was using VT TH from before the taste test).
