I use mostly TFA flavors, don't know what you are into, but I pretty much exclusively vape fruity flavors so these are the basics I recommend:
These flavors are used in small amounts in many of my recipes:
TFA Sweet Cream
TFA Vanilla Swirl
TFA Bavarian Cream
TFA Cotton Candy/E.M/Sweetener
These are flavors that I really like
TFA Banana(Ripe) - Tank cracker, but has an AMAZING banana flavor, spot on.
TFA Blueberry (Extra) - Add this to many recipes, gives a good blueberry hint to your
juice without being too bold.
TFA Lemon - Huge fan of a basic Raspberry Lemonade recipe I have, this with some Raspberry(Sweet), E.M, and Tart/Sour
Many of the other fruits it really depends on what you are looking for, I have strawberry, watermelon, grape juice, raspberry(sweet), and some others, but depending on what you like they might not be exactly what you are looking for. I find the strawberry isn't great(Like a dried strawberry), I have heard better things about Strawberry(Ripe), the watermelon is alright, but haven't gotten it to pop yet for a straight up watermelon vape. Grape juice tastes like cheap grape sucker, I made do with it, but I am guessing another supplier has a more accurate grape flavoring. Many of these I find are great adding to other recipes, but as base flavors they fall a little short.

I might have to mix that up tonight, I haven't had much luck with a good FV recipe yet. Thats a whole lot of menthol though.
