I'm extremely picky with my juices as well, but my range in flavor interests vary quite a bit. Right now I'm sort of on a "creamy" kick and I've been vaping a lot of Seduce Juice's flavors. Their main line is a fruit based flavor with a hint of coconut, that you don't taste after it steeps. The coconut ends up becoming this creamy feeling when you inhale/exhale and you get a predominant flavor of the fruit. Snake bite (apple) and Snake Oil (pear) might interest you.
If you're into dessert vapes, I'd personally recommend The Vapor Chef. All of his dessert style vapes taste like you're actually eating the food. I got a sample from him of Strawberry VC Cake and it literally tasted like I was eating a piece of strawberry cake. I'm not really into dessert vapes so I can't help you out much there besides listing my personal favorite vendors.
If you want to try "new" things, Good Life Vapor has a great line up as well of all sorts of flavors. I've never come across another vendor that hits flavors so precisely. Even their Baja Breeze which is a clone of the Taco Bell drink leaves you feeling like you just drank a full glass of it. You even get a sense of carbonation from the juice on your tongue, but nothing overwhelming.
If you can catch Bombies while they're open on Wednesdays, I can't recommend them enough but there's only 5 flavors to choose from, 1 being a Tobacco and another being Banana. I'd recommend Seven Seas from them, it's absolutely amazing. By far my favorite vendor whenever I can get my hands on their juice.
