What is the difference between the 510 and the 808? I just saw a review of the Lava Tube and it seems pretty interesting that you can up the voltage and get more out of it haha. Is the Lava Tube used with a cartomizer as well?
I haven't used the lava tube but I think for availabilities sake its a good buy, which is kind of what I was hinting at you getting to start out with as well. I think you would benefit from talking to some people who use the model.
808 is a male threading and 510 is a female threading on the lithium battery, the long shaft that connects to the nicotine liquid containing cartomizer. I choose 808's because they IMO have better cartomizers, at least the ones from Bloog and Smokelessimage.com are fairly powerful. After you get your model the next step will be finding your flavor, kind of like choosing your brand of cigarettes, except with a million more choices lol.
