I did have two tanks that I would keep different flavors in. I'm still searching for favorite flavors, so far my closest is French Vanilla Coffee in the am. and something fruity/sweet in the afternoons. I'm okay with the amount of vapor I'm getting now, at the most I'd like just tiny bit more (I can get it vaping on a higher voltage on what I have, but it makes some of juices taste bad). Mostly, I just want more flavor, a touch more vapor, and something inexpensive so that I can keep a couple of tanks full to switch flavors during the day.
