I like Penny's Girl and Lucky Strike (are we allowed to post the sites we got it from? Idk, answer and I'll post or PM).
tobacco Pure from another site is good as well. The thing I've found though, is not no tobacco
ejuice is really and truly going to taste like a cigarette because of the smoky flavor you get from lighting something on fire. But some juices are really nice.
Getting the hit right is another thing. I like a 80pg/20vg mix, sometimes 50/50. Once in a while I'll use 100% vg, but it's really heavy and tends to clog up your equipment unless you're dripping.
