So I decided to upgrade to the istick from my nautilus mini. Hoping this is a good choice as I've bounced back and forth between a few options for awhile now and I need to make a decision as my nautilus just isn't cutting it anymore. My question is on the tank. I have no idea which one to get with it. I like mouth to lung hits and flavor. But I also would like to play around with clouds too. I've only ever had my nautilus mini so I am still new to everything else. Any advice would be appreciated!
