I've never been impressed with the Juggernaut coils to begin with, way to efficient, and with how their surface area is, they tend to hot spot like a bitch, on top of their power efficiency requirements are way at the bottom of the scale. Best advice, lower down the wattage, check how tight your wicking is inside, if everything there is copasetic and still functioning awfully, tear them out and move to a better coil design, maybe a pair of standard single core claptons. Victim of your own torture and misery IMO.
