The worst flavor I've had so far has been one of the two that I created myself on ECBlend. I named it 412 Brandy Nut, it consisted of 60% 555, 15% Honey, 15% Nut Mix, and 10% Brandy. The only reason I call it the worst is because when I vaped it, I got literally no flavor at all. There was plenty of vapor, I was spewing clouds from my lungs, but there was no taste at all. I've decided to let it sit in a cool, dark place for a while, probably 2 weeks or so, before I try it again. I shake the bottle everyday, as I do with all my flavors, but I was SO DISAPPOINTED because I created this flavor and had been waiting patiently for its delivery to my house. I hope that letting it steep will bring the flavors out, if not, oh well.
