As a matter of fact, I have vaped 5 or 6 tanks of it so far (mixed per original recipe; in the tank as I type).
I agree that the Pink Guava does seem to be center stage... at least fighting for center stage with the Kiwi. I get a citrus bite/twang(?) of "grapefruit" that many mention tasting in the Pink Guava.
I am finding I kind of like this one. It is (as you say) a rather light vape. It is not at all "in your face." The Pink Guave, and Kiwi, seem to take turns with my palate. I can't say that I really perceive the Dragon Fruit. But, in fairness, I would have have to mix this same recipe, without the DF, to understand what its contribution might be.
I
could see, either a slight reduction of the P.G. and/or a slight increase of the Kiwi, in order to bolster the Kiwi's dominese
As for additions; I'm not sure. I like it as it is. I tend to steer away from complex recipes because I often miss what is supposed to be there. I suppose it is just too many decades of taste bud abuse.
I do think it could be an interesting base for a light (gin or vodka) cocktail vape. I also think it could support the addition of a fresh herb... like mint, or basil. A coolant (WS-23, Koolada, or menthol) seems like a natural addition as well. Creams are okay; but I find I am growing bored with them. A cookie, or biscuit could work too. I could even see it combined with a mild tobacco; for those who like a fruity tobacco.
For the sake of others who might be reading this; the recipe Sugar and I are discussing is this:
