So i really have no idea what I'm doing, I just king of do what I can to make it taste good. With that being said, with the 0.2 ohm coils the quad post coil no matter what wattage I use I seem to get cotton. I'm using a 70/30 vg 1.5 nic, and I tried every setting between the suggested wattage on the actual coil and I feel like my tank just hates me. When I use the 0.15 coil I don't have any issues as long as I keep it around 110W. But I would like to use the other coil as well since I have it Sent from my SM-N910V using The Vapor Talk mobile app
