...i would pick clear base lol because every flavor even if u love it and can vape all day long u will hate eventually so if i could vape one flavor all my life i would go for none))
Right now I'd have to go with:
Vapetasia Killer Kustard
It's sosoooo damn good. I can think of others that may make the cut, like Vapetasia's Royalty II, Naked 100 Hawaiian POG or Lava Flow, & a couple others...
But yeah...Killer Kustard would have to be it right now.
