I mix my own liquids. For the Atlantis 2, it's straight VG for clouds, 2mg/ml nicotine, and more intense flavoring. The majority of the flavour concentrates I use are ethanol based. After sitting for two weeks for the flavours to meld, I boil off the ethanol to get a smoother vape. A few big clouds and lots of taste while relaxing after the evening meal lets me stick with my favorite liquid in my Triton or the mini. Call it my equivalent of a cigar or pipe if you wish :)
Subohm really isn't my thing. I like either the 1.2ohm or 1.8ohm coils with my Nautilus and/or Triton Mini.
