I voted EVOD out of the selections available
However, for the past 6 weeks I've been using a Smoktech AVO clearo with better results. It is basically an EVOD with more capacity and made of pyrex--it works better than my EVODs or Pro Tank 1. I'm looking at the Aspire ET-S dual coil to replace the AVO though, I vape a mechanical so use the 1.8 ohm heads for the AVO and hope (please!) that Aspire rolls out 1.5 ohm dual coils. Then again, the Pro Tank 3 is rolling out with dual coils so maybe I can just throw some heads in the Pro Tank? This games moves so fast but no complaints here!
