I took a REOS down to 0.7 once, comes out to 19.5W. Didn't like it- too hot and the flavor of my favorite juices seemed distorted. Could be the 70% VG liquids I order. Either way, I prefer staying around 9W for my HHV liquids, maybe a little less for Highbrow and AltCig juices. Really not interested in 40W, although there does seem to be a market for that sort of thing.
I run my (one) REOS in that range all the time in a Cyclone. It has plenty of air flow to keep it cool enough - for me. And the Zenith I just built at .3 has huge slots for air flow to keep it
relatively cool. Probably not big enough for the cloud chaser crowd, though.
1) It depends on the atty , I keep the Kayfuns around 1.5 , I've played with them and they're not good at subohm , not enough juice and airflow to keep up especially with 100%VG , but 2) pushing dual or more coils can definitely kick the flavor up in other devices , 3) that new DNA40 does go all the way down to 1 watt , and with the temperature control system to prevent burnt juice and wicks it's gonna be a serious contender .
1) I agree. I ran a KFL down to .9Ω once, but didn't like the result. The tri-coil Gus Estia is the only tank I use these days. It does fantastic at the .7Ω I typically have on it. But then, it has juice flow control and real AFC (I never considered the Kayfuns AFC to be useful). It doesn't leak when going from A/C to 90+ degree weather. And it's simple to close the JFC and AFC if I think there's any chance of leakage.
2) I agree. I usually have duals in my drippers, since they're easy to build and really taste good to me. But when I use MM or Zipper wire, one coil is good for me. Heck, that 0.3Ω, 6 wrap Zipper is HUGE!
3) I agree. While I enjoy the DNA30, I don't much care for it's limitations. It looks as if the DNA40 fixes all of the things I didn't like about the 30.
And I can't wait to try one for that TC feature. All to often, I try to get just one more vape than I should on a drying wick. Rayon helps a lot in that respect, but I've been known to burn a rayon wick in half, too.
I do want to add that Evolv did go a little too conservative for some at 40 watts , there are people that like to run high resistance coils at higher wattage to get the effects of subohm with more coil surface area , and better battery life , that's something I'd like to play with but 40 watts is a little on the lowside for that . Gotta see how that temperature control plays out though .
I wondered about that, too. I
might try one of those high watt regulateds, but there aren't any that are tugging on my wallet strings yet.
