Excellent tutorial, Drifter!!
Have you any other tutorials? I hope to find your lesson with the dual coil rda. (nudge nudge![]()
What would you want to accomplish with dual coils?
More vapor? You can do that by making a micro coil with lower gauge wire. If you need more vapor than that, you're not human
Cooler vapor? Same, lower gauge wire
Responsiveness? Loops of the coil touching tighter.
Besides that, the other features I can think of are negative, such as poorer air flow, 4x more resistance wire, and more difficult to get working well
