And I don't use dual coils all the time because the Darwin can only push them so far. I actually prefer 2.5 ohm single coils at 9.0 watts. I've been doing this a good bit longer and know that many vets found right around 5.0 volts is the sweet spot. The dual coils make a nice change of pace but when I have used them on 5 & 6 volt PV's they perform the best.
And I don't agree necessarilly that your nicotine comsuption is greater. Your total nic consumption will not necessarilly be greater depending on how much you vape, which in my case is less when I vape around 5 volts. My "clouds of vaper" are the same whether I'm using a dual coil or a single coil. And my eliquid usage is the same regardless of what cartos I use. There is no way you can prove that assumption, which makes it irrelevant to the discussion.
This has got me thinking, which is not always a good thing, but when it occurs, I like to keep it going.
I have long since gotten over any fascination I had with dual coils, ESPECIALLY on low-voltage devices that IMO can't get the lowest-resistance dual coils warm enough to vaporize all (any?) liquids properly.
The discussion of juice consumption makes me wonder if this might be a good way to look at it. Dual coils on a PV/APV that can power them properly (4+ volts and up IMO) might be like having a V8 engine on a car that would do just fine with a 4-cylinder turbo. Massive clouds of vapor are cool and all, but I think that quality of vapor production trumps quantity, and I don't see really needing any more vapor production than a single coil, at the optimal temperature, with optimal juice delivery to it won't produce just fine.
It also seems to me that a single coil in a tank/carto would have a better juice feed going on that the upper coil of a dual coil, especially when the tank starts to get low. Having an "upper slot" and a "lower" slot in the carto (not really done, I know) would do nothing to change that. And with a single coil, your battery is obviously going to last longer. Fewer watts per vape. And does a single vape with (2x) cc's of vapor get (2X) the nicotine into your system than one of (x) cc's? Somehow I don't think so. A particular nicotine molecule either attaches to one of a finite number of red blood cells present on x square centimeters of lung tissue or it doesn't, and IMO an overabundance of nicotine molecules in some monster hit isn't going to change that.
If one is good, two is not necessarily better. Make mine a single, please.
