I am new to vaping,10 days ago I stopped smoking cigarettes after 20+ years. I have tried patches, cold turkey etc.. Those attempts ended up being more how long could I go without a cigarette then feeling that I had quit, it was a constant struggle. I am loving vaping!! I haven't had any real urge to smoke and am very much enjoying the hobby and flavors!! However.... I am killing the ejuice ! I got a Smok priv 2 mod. With the prince tank. This thing is low mpg! I like the clouds but I care most about flavor and thick satisfying vaper. I have a crown 3 on the way just to try something different but I think this is also a guzzler. I smoked a pack and a half a day. So I Vape a lot. I'm refilling this tank many times a day. I do not want to build my own coils. But I do want efficiency without having to give up thick flavor. What is the most efficient tank going as far as not using alot of juice? Preferably one with the best flavor. I don't care if there's giant clouds or not..Thanks!!
