So I've finally got some DNA40 boards that work. The Eviva with tempered 30g nickel spaced coil on medical rayon ball wick, chain
vaping 5-6 drags, the Eviva feed keeps up like a champ. Also: some attys will not work with nickel builds, as the contacts are not good enough to get the precise resistance needed to monitor temperature. The Eviva's resistance is rock solid at the original 0.14 ohms measured when I first built it.
I really want to say that I have moved on to squonking and will never touch a
tank again, but seriously, this tank just doesn't want to annoy me like almost every other tank did.
This is not just quality, folks, it is actually thinking through and testing a product to death. Fantastic.
