This is my third coil I've built for the nautilus. Following Rip Trippers tutorial I built my first at 1.6, the second I built a 1.4 and today I built a 1.2. 6 wraps with .28 kanthal and wicked with cotton. I've got it on my Lavatube 2.5 and vaping at 14 watts. No burn taste, very warm vapor and a hell of a lot of flavor. Love this tank!
