GeminEye, I'm also an MTL tootle puffer, and I think the best tank on the market right now is the GS Air M. I have a couple of Nautilus minis and like them. They give nice flavor and a nice vape. But I think the GS Air just blows it away. And the coils last a whole lot longer. On top of that, it is really inexpensive - about $10 at Sweet Vapes. We have a big long thread on the GS Air that you might want to check out. A lot of nice people, good conversation, and a lot of help should any problems come up (and I've had very few with this tank). Here is the thread:

That thread is up to 586 pages, so you might want to start at the end.
The Atlantis and Subtank are great tanks for a lot of people, but not for people who do MTL. Even though you can turn their airflow down. They just weren't made for MTL vaping. Better to get something that is.
OT: Did you get your Disrupter yet? I won mine a couple weeks ago and am still waiting for it.
