Halo Smooth 8 for me. It's said to be a non sweet Ginger tobacco with a good throat hit. I hate sweet liquids, so this is my everyday/all day liquid now for over a year. Totally Wicked carries the exact same thing in their Patriot line called KaMel (and has the flavoring only liquid for those who like to DIY or cut their liquids).
I also will vape Halo's Freedom if I have a bottle of it around. Has a mild cedar like tobacco flavor (that some people seem to hate). Hard to explain. Different, but very good. I happened to fall in love with Smooth 8 (I got samples of everything when Halo first opened up), and stuck with it.
All of Halo's menthol line-up is really very good (I just don't vape menthol much anymore). The ONLY liquid I like a little sweet.
At least these flavors/Companies are consistent. Pretty important to me, as I got tired of other companies constantly changing what I liked and getting a completely different flavor when I went to reorder.
