I have been vaping for around 16 months. The past year of that has been with a reo, which I do like a lot. Recently I have decided I want something else, in addition to my reo. Something a little more sleek, a little smaller, and preferebly vv. I am almost sure I will go with Provari mini, but I will want to get a tank system and I have no experience in this realm. My question is how do I know which cartomizers will fit which tanks, and vice versa? Also, what do you recommend for a tank setup? Which tank? With what carto? Ohms? Etc, etc.. I don't want to go with a cheap setup, nor do I want to go ridiculously expensive. Somewhere in the middle. Keep in my this will be going on a provari. Thank you for any input and advice you guys have for me!
