FlavourArt is top notch for me. It's the main brand of my stash. f you like fruity flavors, true fruit flavors, then you're bound to like theirs. If you want candy fruity flavors, then you'll probably like Capella's or TFA. I have FA, TFA, Inawera, Hangsen and a couple other brands. FA is my top choice is most cases.
I get my nic from vaperstek, but I hear pretty good things about My Freedom Smokes nic and also Nude Nic.
