What do you guys do when you get a sample of a juice you have not previously tried? Right now, all I have is 2 Aspire Nautilus tanks, both of which are currently occupied with their own juice. I received an order of juice today, one is a flavor I already have, and really like; the other is one I've never tried. So, when the rest of you find yourselves in the same situation, do you empty and clean out one of your tanks to try the new flavor, or do you use something like a cartomizer to try it out? I don't want to go through the process of flushing out a tank, refill it with a new juice, replace the atomizer, and discover that I don't like it, only to have to flush it out again, put in a new atomizer, and fill it back up with the juice I had in it before. Suggestions?
