Let's see, at the moment I've got a dozen tanks (marked with rubber band colors that match the bottles for what is in them), and 4 rda's all set up on my desk. When I go out every day I've usually dripped enough to choose my mood, and take 3-5 flavors in tanks to enjoy while I am out and about. Back at home, the rda's tend to gather a set of flavors each to rotate as the cotton is ready for more.
For tasting steepage, I set up a row of rda's with fresh cotton short wicks in em, and roll by the numbers.
Vaping is more than just a hobby; it is a passion =)
