Here are the three I would like to try most at this point:
Ahlusion
House of Liquids
Darth Vapers (should have an order arriving soon)!
The two that I've tried most recently are:
Mountain Oak Vapors -- I've only tried their Applewood and a couple others briefly, but they have a really nice velvety texture and a nice muted sweetness to them.
Heather's Heavenly Vapes -- I ordered several tobacco flavors (Gandalf, Pirate's Booty, Dark Horse, Huntsman, and Dragon's Fire) and Mayan Apocalypse. The tobacco flavors were all fairly similar, using a base that is on the 'grassy' side, but they're all wonderful and the vapor has a rich, creamy quality, which I enjoy. Gandalf and Huntsman were probably the two that stood out the most. Mayan Apocalypse, I was not terribly keen on. A darker, richer, drier chocolate would have made it better IMHO, along with more of a roasted red chili spiciness.
Thanks for starting this thread PawpawBrett!
