Okay so I bought the crown tank at a vape expo got it for a decent price so I don't want to complain. But if I take long hard hits I sometimes get a burnt taste. I also noticed that my coil goes from .25 to .29 when taking longer drags. Yes I primed my coil I'm not new to this lol just trying to figure out what's going on. I'm vaping the dual coil .25 I believe what wattage would be recommended for this coil? In my opinion if the herakles tank was top fill I wouldn't want any other tank lol but since I have the crown I want to use it but I want it to perform like everyone says it does.
