I do agree it is kina a caramelish-
tobacco blend but then again: Isn´t it also a bit too much on the 'cotton-candy' side, as someone suggested.
My personal re-interpretation of it is as follows:
1/4 US mix, 1/4 vanilla (a pretty strong artificial one pref.), 1/4 mint (The chemical taste ones...), and 1/4 of whatever e-
juice at hand (Preferably once you want to get rid of...)
.....and there you go! Your own home-made cheap class-B version of the popular RY4. Mind you it won't taste that similar but.... who knows? I have named this recipe: Caramel Circus. I kinda enjoy it, but keep it mostly as some back-up juicy!
