We're everywhere!Oh gawd, another one of "them"......![]()

Yep. I built one the first week the DNA40 was out. It was my most used mod for a bit over a year. Then the board died. No problem, I have plenty of spare boards (as I'm sure you know from the CoOps), and since I built it to begin with, I could certainly have replaced the board. Except I never bothered, because for me, mechanicals vape just about as well.I have seen some nice compact dna squonkers though, just not my cup of tea.
FWIW, my builds are practically identical. 3x30 twisted, 7 wraps, 2mm ID. Of course with Kanthal on a mech, I've got about 3x the resistance I had with Ti on the dna, but the amount of power and therefore the heat flux is about the same, as is the wicking (rayon). So one might deduce that peak temps are about the same as well, and I never hit temp limit on the dna unless I did something wrong, which wasn't often. No, I don''t really know what the 350°F I had the mod set to really was because the DNA40 didn't have a calibration for Ti. But I do know it only produced the slightest discoloration on dry rayon...
One thing that's better about mechs (at least for me) is that I'm not tempted/able to turn the power up to compensate for an aging build, something I very much had a tendency to do with my DNAs.
Anyway, there's no question that temperature is important, but I do believe that with builds using a conservative heat flux and good wicking that's kept wet, TC isn't needed to keep coil temps under control, at least not the way I vape.
Maybe one of these days the DNA60 will actually be available and I'll get motivated to fix that mod, and do some more experiments. Unfortunately, DNA75s do not work in the form factor I desire.
