i always have wick burning taste issues with wick based tanks. no matter how low i set the voltage, or how far i dial down the kick in my stinger, i can't seem to get awy from it, and i have tired it with numerous resistance coils, and i can't get over that burn. it's a real shame, because before i upgraded, and upgraded, and upgraded...the only thing i can use with those joyus little juice whores is to use them on my ego twist, then, for about the first half of the tank, it's a stellar vape. great taste, great vapor, great throat hit (depending on whether that's your thing). same for the standard size ones...work great on the ego twist (look strange), until about half a tank. i attribute this to wicking well and doing what they are supposed to do, but i've got to find an answer to this issue.
