Tried kanthal in power, Ti and SS in TC. Sometimes it has some quirks, like it works like crazy on a fresh coil on 150 then gradually goes to crap until its fine at 270-280. On the other hand, i've had the same twisted Ti build in it for weeks, works flawlessly. Still trying to figure out what causes this.
On the mtl note, the mod won't affect that much, it doesn't regulate airflow in any way (except for bottom air fed atomizers). The atomizer will. I'm a mtl single coil guy, my main atties atm are veritas with a single twisted vertical and a nectar with a single spaced. If you got more questions feel free to ask
