Vanilla Mint is my current favorite. Also really enjoing Smooth and Robacco Menthol, all from Blue Mist Vaping.
Also on the rotation for when I need something sweet or just, different:
Bounty Hunter, Jamaican Rum, Big Island Drink, Cherry Ice, and Mojito. I also have perppermint and hypermint, I've heard great things about the hypermint, but sadly, forgot to change the nic content box on the order page so have this in zero nic strength! ah well, I'll just save it for when I cut myself down gradually to low or sero nic.
