I'm new and my first vaping setup is an Innokin iClear 16 clearomizer on a Unique "firefly" battery. I would like to start trying new juice flavors....my question is....Should I use separate clearos for different flavors? Or can I just vape the tank to empty and add a new flavor. (I fear the the old flavor in the 4 wicks will ruin the taste of the new flavor) Great place you guys have here, Thanks in advance for the help!
