Personally, I love tobacco flavored juices with a hard throat hit. I've tried Janty liquid and love it, but when looking for a great flavor and kick combo I've been left out to dry except for a select few. Here's my faves-
Dragonflyecigs.com - Camel 24mg nicotine juice (Wonderful! I've been vaping it nonstop for two weeks!)
Tastyvapor.us- Tobacco 24mg- Very much like a cigarette except the smell lingers in a room if you're vaping for a constant hour or so..
And for a great fruity one, I've come across Nhaler.com's Pear lung juce. Delicious, delicious, Delicious. Really. Just like a pear. Not too much throat hit, though. Goo nicotine high and the juice has herbs in it that (they claim) benefits the body.
Hope this helps!
