Awesome. That was the answer I was looking for.
Bad, one thing I saw on Steve s review about dual coil ce2 s was that the top coil tended to run dry. I have a couple of solutions that might work.
Obviously, the easiest would be dual horizontal coils, but that might make the form factor larger than desired.
The other is slightly outside the box. Well, not really, just not "normal." If the wick has more issue at the top coil, which could be due to some of the liquid heating up and vaporizing due to the vapor coming from the bottom coil, use different ohms per coil. Higher ohm top coil with a lower ohm bottom coil.
Just a thought.
