Single or Dual?

[KenS]

Got my sigelei in yesterday, WOW what a difference from the Egos, even with the cheepie cartos.
Now, I'm looking for a good tank, but would like to know about single vs dual coils.
Is a dual better? Does it drain the batt faster? What's the difference?
Want to stay away from the ones you have to drip, can't use that at work "under cover"
Would also like to keep with the bottom coil like the Pro mini, don't have the problem of the "slurping", seems to not clog up like the top burners.
TIA

Dual coils create more vapor and go through eliquid much faster (makes sense, you are vaporizing twice as much each time you hit the fire button)

more vapor = tougher to "stealth" vape

lower ohm heads will drain battery faster regardless of dual coil or single

aspire nautilus tank is getting rave reviews from most people and has air flow control (I use a protank 1 with the new aero base - works great)
