The thing about AiV is finding the right "spot" to vape on your gear. I am a bonefide "Lemon Loves Cake" fiend. I have samples from "A Little Bit of Everything" that I haven't even tried yet because I've been enjoying the heck out of "LLC" and "Zombie Apocalypse". Put my 3rd order in this past Tuesday. Uh, 60ml bottles

So, that being said, I think these are the things to consider when you're vaping AiV juice (or any juice):
1. How long you've been analog free (I've been since the first part of January '13 and my "buds" are still tweaking!)
2. Your delivery device (ohms, volts, watts, BC, TC, etc, etc.)
3. When your main juice that goes "Pow" becomes too much and you're looking for something that has hidden tastes that sneak up on you, AiV is a great option.
4. To steep or not to steep. I can vape this right out of the box, but letting it sit for a week or 2...is it our "buds" still re-grouping to their former self? If I take a bottle that's been sitting there for a week or 3, the flavor is even more mysterious.
5. READ THE REVIEWS! "Cherry Blossom" is not cherry tasting, it's more of walking through a cherry orchard when the blossoms are in bloom, a totally different taste. Names can be deceiving and your mind will be thinking one particular "taste" and your mouth will be registering something entirely different. (I found early on that reviews for any vendor help incredibly!)
I want to enjoy what I vape, AiV hits the spot for me, and saving $ is not an issue with juices at this point. Have many, many samples from other vendors that I tried and, although some have been pretty good, nothing that hit me as an ADV.
