There's gotta be more than TFA, LA, FW, FA, HS and CAP right??? Guys???
Inawera and Faerie's finest aren't on your list, I've also seen a recipe with Watkins Cherry. I can't vouch for any of those however Inawera is supposedly good, and I heard about Faerie's finest a lot on ecf but haven't heard of them in a while.
Edit: Just remembered about Vaping Zone, they have a bunch of super_concentrated alcohol based flavors that get great reviews, you could make a completely PG free juice with those. Ecig Express also has a line of tobaccos and fruits, their black mile + gets great reviews along with other tobaccos, don't know about the others though.
Double edit: Ecig Express also has tasty puff and jungle flavors.
Nature's Flavors: available at ECigExpress
They look so enticing! Can you vouch for their taste accuracy?
I've only tried their Pear... it was as good as pear gets: one of my favorite flavors, but hard to capture in an extract.
If you want to nail down a flavor- and $ is no object (ha) - you could consider buying the same flavor from different companies. Everyone's take on a particular flavor is going to be a little different, hitting slightly different notes.
tasty puff (don't go to this website. it's annoying. go here instead)
I recently tried a couple of flavours from Crave Gourmet's DIY section after winning some free 0 nic juices from them in a contest. The juices were lovely, even at 0 nic. The DIY flavours I got are actually quite good, and are sans PG (French Vanilla is creamy and mildly sweet, Danish Pastry is heavy on cinnamon, and I suspect part of the base to one of the vendor juices I used to love). Shipping took a bit longer than I thought, but customer service is good. I'm still working on a few recipes with the 2 I got. I would order more from them for sure, but probably not often as they only sell the DIY in 30mL bottles at about 12 dollars each. Also Inawera seems to be getting decent reviews. Haven't tried them yet.
