you should definitely take a look beyond tobacco. I was kinda surprised by the flavors I chose and again with the ones I chose to keep around, much less the crazy number of vendors and varieties.
I started with tobacco varieties, too. 555 stood out for me and was my first large bottle purchase. then I found a local vendor, picked up some dessert flavors and ordered more online. I found a couple of good vanillas out there, but attempts at chocolate were unsuccessful. so now I'm not really on the fence with my go to flavors but am really liking biscotti and apple pie and cherry cream and a really great tea as diversions. vanilla is my current choice through the day, but in the evening with a cocktail I'm looking for the 555.
I haven't found a carto / clearo killer yet, but I suspect the caramel I found locally is responsible for a dead ce3 - could be that I was power vaping it.
