That makes perfect sense about the larger heating area for a micro-coil, and why the Cisco was peforming so well at 3.5ohm - inside, it had a coil that looked like a micro-coil snake. I've never seen such oddness in my life, but there it was. The coil spanned the whole bottom chamber, it was like a ECF microcoil gone steroid mode. And at 3.5ohms, the vapor was huge, the nicotine hit was extremely soft and velvety (but surprisingly, the nicotine absorption was better than any device I've had with a throat hit), and the flavor was truly, plain truly, out of this universe.
It could be the issue all along, so thank you so much for the advice!
And yes, the NET's gunked up that high-ohm microcoil in about an hour - I was able to vape it a little past then, because the NET crud still tasted pretty natural, but finally it got to the point the atty was running pretty dry with all that gunk, and cleaning the dripping atomizer was not something I could tackle. However, if I had a good sturdy microcoil in an RDA, I wouldn't mind a bit cleaning every couple days - getting a good result out of an NET, it's like heaven. Pure and simple. I'd do whatever I'd have to do to get it, because it just lights my brain on fire. The tobacco layers of NET's are just... unreal. In a good way. It's like vaporizing every flavor you love and smell in a good pipe smoke, but soft, but clean, but pure.
My current mod, the MVP2, doesn't fire above 3.0ohms, but I'm hoping that I can build a say, 2.8ohm microcoil, which may help a bit more with gunking, but still giving the flavor and soft nicotine caress I enjoy (which, with nicotine caress is soft, I love high nic!)
For anyone who enjoys NET's, I know this isn't the place, but try Indigo's Captain Ron - it's not an NET (I don't think...) but at a higher-ohm and full flavor, it vapes just like a bag of fruity pipe tobacco smells. Exactly the same. For any NET'ers who are looking for an extraordinarily unique juice that reminds them of another factor in the pipe tobacco world, this juice is just unreal. It may actually have a little NET in it to give it that smell realism, not sure. It's a fruit juice, but it's one that would spark the memory and sensory complex of anyone who enjoys that fruity, deep smell of a bag of Cavendish or so. Such realism.
So glad for the help, and as always, any advice at all is appreciated!
