Howdy Dustin, I just gotta give ya my 2 cents as well.
I started with vivi nova minis, I still use them as well as a couple of large vivi novas. Moved to RBAs and have played with RDAs. When I tried carto tanks (on and off, in between the list of what I've used), I always had problems with gurgles, leaks, burnt taste, ect. I never used cartos by themselves. Use these on my lavatube, zmax, and a few different mechs, home built mods, groove, gripper, twists, ect.
One night I was having problems sleeping, and got into a conversation with another who wasn't able to sleep that night. We talked about a number of things, but he was a carto tank guy that had answered a couple of questions for me in the forums. We talked a bit about carto tanks, and between that conversation, forum posts and his blog posts, I was told what I was doing wrong, how to correct it and now carto tanks are my main nic delivery device. I don't have expensive tanks, a few from IBTanked, an Artemis or two, a couple of boge F-16s, a few other unidentified tanks (just don't remember where thy came from) nothing special. I have some boge cartos, some smoke tech as well, and have tried others, I buy them prepunched. If you keep your eye open you can get them at very good prices, especially if you are willing to buy a batch of 50 or more.
I can and will only speak for myself, cartos tanks are the way to go. Easy to use, great flavor, no hassles, not time consuming. My vivis have their place....I rebuild the coils myself, the small ones I use the same type wick they come with, use these to test new juice, easy to clean, don't have to replace heads all the time and good for testing. The large ones I use cotton to rebuild, and use occasionally, especially with my daughter bogarting my juice. When I find the right taste to juice I'm trying to DIY or purchase, then it goes into a carto tank.
Good luck, do whatever pleases you, do what is best for you. Read the links that have been provided in this thread.
Oh yeah, that guy who couldn't sleep.......it was Baditude. Thanks once again my brother. For me, you made vaping what it should be...easy, enjoyable, with a repeatable experience.
