For the record, it's not me calling it the Kayfun killer. I'm just quoting the local b&m store and the daily vape deal site (whose name is banned from being mentioned on ecf for some reason... let's try: .........)
On paper, it sounds like it may be superior, but I'll wait to actually try it before I make that claim. As far as it being a juice & battery killer: in theory, a shorter puff gets you same amount of vapor using the same amount of juice and power.
Oh no, I followed your link, I know it's not you coining that term, it's advertised as such.
As far as battery, With the devices/builds used today it can be exactly the opposite as far as battery life. You can set a 1.5ohm dual coil at say, 10w (2.6A) and on that same note a 1ohm single coil at 10w (3.2A) and that 1ohm single coil will drain your battery quicker. As far as juice, well dual coil has more surface area, but a hotter single coil can also suck up a lot of juice (parallel coil?). I guess what I'm saying is there are more variables to contribute to juice/battery life than dual vs single coil.
@Loomeye not singling you out I just happened to quote you before my ranting

As far as why that's censored, it never was until the other place he runs opened. It's just another division in the vaping community if you ask me. We should be unified at least while we are fighting to keep our right to vape. But what it really boils down to in my eyes is money. One place sees another as a threat. And in the end this is a private forum and they set their own rules.
Not bashing either forum, just my take on the whole thing.
