I like bakery/desserts and sweet and flavored tobaccos. Not much of a straight fruit vaper unless it's mixed with some creams and whatnot.
If you just want to try a couple FA, go for the creams to enhance whatever flavorings you already have. After you try FA creams, you'll be back for the rest
bakery supplies: Apple Pie (for the great crust flavor), and your favorite fruits to mix with it: Peach, White Peach, Fuji apple (beat Apple IMO), Bilberry (like blueberry), Strawberry, etc - which ever you like best. If you like coffee-flavored desserts, add Tiramisu and Vienna Cream.
cookie supplies: Cookie and additives: Caramel, Butterscotch, Coconut, Lemon, Maple Syrup, Cocoa, creams, etc. - whatever flavor cookies you like best. You can also use Cookie with Apple Pie for tasty crust flavoring on whatever you're mixing.
creams: they go with tobaccos, pies, cookies, and fruits, and I'd recommend both Fresh Cream and Vienna Cream at minimum, and add Catalan if at all possible. That gives you a plain cream, a sweet and rich vanilla cream, and a slighly spicy slightly caramel cream. Between the
three, you can make almost everything delicious.
fruits: FA's are realistic fruit flavors, not candy-tasting. Banana and pineapple are less strong that others you might have tried, but taste like the actual fruit. Just pick up a few of your favorites, along with some creams and Meringue (for sweetness).
other sweet stuff: Maple Syrup (for your cookies and
tobacco, if you like maple), Meringue (excellent sweetener for fruits, especially with a little Fresh Cream), Peppermint (very pure flavor, a little creamy, a bit sweet, great alone, mixes well with many fruits), Anise (if you like white tic-tac mints), Cola and Black Cherry (for superb cherry Coke), maybe Honey (exceptionally sweet, exceptionally strong, very true flavor - nice in tobaccos as well as the usual uses)
gotta have: Vanilla Bourbon, just get some! Vanilla Tahiti is a different, more exotic flavor and goes great with fruit. Classic is sweeter but less complex than Bourbon. I think Vanilla Bourbon is the most 'gourmet' flavor of the three, most different from other brands. All are great!
misc: if you like coffee at all, get Espresso, Fresh Cream, and whatever flavors you like in your coffee. If you like nuttiness, I recommend Marzipan for sweet almond or Nut Mix for an assortment, or Hazelnut for strong and perfect hazelnut flavor. If you like tea, Black Tea is the one to get.
boozy: The Jamaican Rum and Irish Cream are absolutely delicious, plain or as additives. I couldn't mix much without them, especially the Irish Cream.
I like sweets a lot myself. There are some recipes on my blog, if you want to see what flavors work well together, and get a feel for the percentages you'll need. Lots of recipes in this thread, too!
