I'm trying to develop flavors for me and have had commercial juices with one flavor on inhale, and another on exhale. After a year I've decided to experiment with flavors, testing as stand alone. Now I want to combine flavors to get that in and out flavor. What does this, or how is this accomplished?

I have a pauper's set up. Alien box, running either aspire, crown. Both .5 open full at 60.

Any help would be greatly appreciated.
