Hi fellow Provarians, I've been using Kanger PT2's for all these months. No complaints for the most part. But maybe I'm cheating myself out of a better vape experience, so I would like to try the ibtanked system. I've read Baditudes blog, it was very helpful. Maybe some of you nice folks could give me the exact mm size tube and size or type of cartomizor for the size tank that fits Provari (with out the Provari ring) I would rather buy everything from just ibtanked, but if the cartos they sell are somewhat inferior, maybe recommend another brand and size. single coil 1.8 to 2 ohm is fine by me. I need large ml juice capacity if at all possible. No problem refilling once or twice a day. But I don't want to refill every hour, know what I mean? I would probably buy 3 tank sets, and maybe half dozen cartos, just to have spares. How long do they last? Do you clean them and re-use? Or just use until they die? Thanks for your help.
