I started using an rda so I mix all the time. I only have one for now, until my next FT order gets here. I am not going to change my wick every time I want to switch flavors, so I have several fruit types and a spearmint and Hawk Sauce and Thug juice from MBV. They all go well with each other for the most part and I will throw in one flavor and vape a little then add a drop of this and a drop of that the flavor just keeps changing as you vape. I haven't had one yet that I did not like. I also have a 100%VG apple that is kind of flavorless and I throw that into the mix if it gets a little harsh. Two of my juices have great flavor but a little too much TH. The ability to do this is one of the reasons I have fallen in love with my rda.
