Hi. Real quick question one. Is anyone knowledgeable with this set up? If so I'd like help with vw vs tc modes. As they relate to the HW coils this low end mod uses. Any help would be greatly appreciated. Right now I'm using the HW4 (quad cylinder, 0.3ohm,kanthal wire I imagine) and I have a package of the HW3 (tri cylinder 0.2ohm). Been vaping between 50-70 watts with both. I also upgraded the firmware to the latest af software. Thanks in advance.
