I don't really use coils that complex, but things I would try are tighter wicking and or higher wattage.I decided to try something new and bought 20ft of 2x(26-36) ni80 Juggernaut wire from Wotofo, but all I'm getting so far is massive spitback- tiny hot balls of liquid shooting from the coil in every direction. Unbearable, especially with wide 810 drip tips. I'm either doing something wrong or it's simply a crap wire pattern.
Sometimes there is just too much liquid sitting on the coil, or it is being vaporized too slowly.
