It's been a long time since I built my own coils and when this tank came out it had every feature that I wanted in a tank so I jumped on it. Been trying to like it for the past 4 days, but I'm not overly thrilled with it. Been using 26 ga. SS316l wrapped at 3mm contact coils comes out to .6ohms. Using KGD cotton to just inside the tank. Seems to be wicking fine but I constantly get a metallic taste like hot metal. Tried from 20w up to 35 and it only gets worse the higher I go. What am I doing wrong. Checked the coil while pulsing, glows from the middle out both legs have no glow. Any advice you guys have would be much appreciated. Also seems to sizzle for a second after I let off the power.
