In my experience NO flavor stands well on its own. They all need a little tweek of something. Even double ry4 is greatly enhanced by a few drops of vanilla or caramel or even some type of cream. The trick is not to overwhelm your base flavor.
I started out by mixing single flavors and trying them on their own. Then I started taking my base flavor mixing it say like 18mg and adding a little of this or that from the other premixed flavors. If that makes sense? My first successful Swedish fish was 3 premixed flavors mixed together. It's like cooking - taste it - add a pinch of this - taste it - add a dash of that etc.
That last calculator I linked to allows mixing bases together and it'll figure out the percentages for you. That's why I want it so badly.
Not crazy about it but ... whatever.

I even disconnected the power and the co-ax from my "cablemodem" but it did no good, I still had to stand around screaming at it to connect for over an hour. That's the 2nd time this week!
