I have some solid Genesis wick/coil builds under my belt, but after half a day of vaping it tastes like a week old gunked up, burned out carto, and burned e-liquid. 1/8 SS mesh wick (not a straw) 0.5 ribbon A-1 Kanthal, 5 wraps at 2.0 ohms. Using both unflavored e-liquid, and natural tobacco extracts with no difference.
