I have recently gotten a carto tank. one from totally wicked and also a j- tank. i find that the flavor of the juice is gone! except in cinnamon or high concentrated menthol. I have tried it on my ego batt and on Liberty flights vv mod. still now flavor on higher volts, and vapor don't seem to change either. Is this in my mind and my taste buds wacked, or is there a trick to the carto tank.
