I should have stated the Submarine with the 3.0. Right now I am using the 4ml with a 1.5
Hey Corpa!! So nice to see you again! I was confused! Are you loving the lavatube?? I am, hope you are too. You can use whatever ohm carto you want and set the LT to whatever you want and it will auto adjust itself down to where it needs to be. So, if you want to do higher voltage vaping, you should get the 3.0 and it will allow you to go high. If you use the 1.5, you can set it at whatever you want, but the LT will adjust the voltage down. I do have an under load meter and I could actually experiment with that, since pop so generously sent me a 1.7 ohm and a 3.0 ohm.
