Not sure on the best way to change juice flavors. I have a e grip that I just purchased the new rba kit as well as a ipv2s with the Atlantis on it. I tend to like heavier flavors like coffees and Carmel's over fruits. Should I just cross over flavors with both set- ups so at least change the cotton on the rba? Coil changes on the Atlantis will get costly. I'd happily listen to any thoughts you might have on this. Thanks
