The tonic line is really good. The mellonica and tango tea are 2 of the liquids that are in my rotation. In fact, mixing the two makes a really cool flavor. It's hard to explain, but it fruits up the tea.
If you try both Cash and Tonic back to back (but in different atomizers) you will be able to see, and taste, the difference. I would love to see a cherry or redbull-ish type of flavor in the tonic line.
