hello, I got a snow wolf 200watt TC device for my birthday, and got a tfv4 and starre FREEMAX Aswell. I used the .... out of the quadruple and triple coil heads on the tfv4 so I purchased a Uwell crown tank, and I've been trying out the 0.15 ohm ni200 coil heads. What's a good setting for a nice warm flavorful vape? I've been experimenting at around 530-550 degrees Fahrenheit and at 70-100 watts. I'm just curious what's the highest I can run these coils at? What temp and wattage? Thanks. Also, would there be more vapor production(clouds) if I were to use the DVC 0.25 coil heads over the ni200 0.15 ohm coils?
