My current setup I've had for the past year+ has been a 6.6V Bolt running a 2ohm dual coil cartomizer. I'm no longer as pleased with the flavor as I was, and I want to move into a polyfill-less system like a bottom feeding Protank. Still looking for large clouds, but not confident enough in my ability to wrap my own coils. I'm looking at purchasing a Kanger Protank 2, and am debating between a Provari or a Vamo to run it. Which would be a better choice? Are there other mods I should look at? Please keep in mind my priorities are cloud size and flavor potency.
