Carto tanks are what I landed on. I started with vivi nova's when I first started vaping and they are great until you find what else is out there. After trying almost everything, tank and atomizer wise, I use standard size Boge LR (Low Resistance) in a Kir Fanis tank, punched myself. I fire at about 3.8-4.3 volts on my Provari. Perfect.
Pros- $ Cost , Great taste and vapor production, CONSISTENT (that's huge with me), simplicity with efficiency, low maintenance for the most part, great for chain vaping, a whole lot less flooding
Cons- Learning curve but very easy to get used to (mostly priming), punching
How much are you looking to spend on a tank? If you don't mind paying I'd look into Vapourart.com their SnP tank is killer. Terrific fill system and high quality materials.
