Peanut Butter (if you like sweet then get Graham Cracker too and mix them together)
Pink Champagne is a light strawberry with a bit of fizz, some say it tastes a bit like Ginger Ale.
Vanilla Cupcake is okay, but it wasn't fantastic to me.
Aging or Steeping is very important, if you go 100vg then I would expect at least a month to age, possibly longer. Others will have to chime in on this. Or a good amount of time in an Ultrasonic Cleaner.
You can also get verified and sell off or PIF the ones you can't use.
MiaRose I think is also going 100%VG (and Opal already has, thanks Seanchai!) and they might be able to offer further assistance as well. Seanchai has a guide to steeping in his signature too. I have a couple of chocolate types that I am sitting on as they are very dark liquids and require more time to age so I can't comment on those yet. Please keep in mind that with 100%VG aging/steep times will be longer than normal as it takes VG a bit longer to blend well with the flavorings. PG is used because it offers a decent throat hit and it absorbs the flavors faster.
I was where you were at back in the beginning and spent hours upon hours researching and reading what others here really liked because I had spent a lot of money on liquids that were just okay and was becoming discouraged (and broke).
The good news is that you might be able to try a bottle of unflavored 100%vg at your nic-level. A lot of people use unflavored and find it has a slight sweetness to it. This will give your flavored liquids time to age and prevent you from becoming too impatient.
