I fitted my Boreas V2 with dual core clapton coils. SS 316L 26g/32g at 0.12 ohms. I have the Polar set to 70W at 210°C. I wanted to bring that tank as close to the mesh Cascade tank. It’s quite big improvement!
I’ve never used the fancy wires other than making twisted, so I decided to try making clapton wire and the first try came out very servicable. There’s a small imbalance between the coils, but not enough to hurt it.
