I'm pretty new to this, and am experimenting with new flavors. I have my adv vape, which I use in an Aspire Atlantis with the 5ml upgrade, then have another Atlantis, and have a Triton on order. I was wondering if anyone has ever bought a set of some of the more inexpensive tanks just to have a separate one for trying new flavors. I've seen them on Amazon and fast tech and was just curious about opinions you all might have.
