I've been excited about my flavors for about a week now, and I finally got to mix what I was planning today, and it turned out pretty good!
I've wanted to try and make something similar to Black Out City from Bombies. It had a certain kick to it that I hadn't had in an e-juice before, and figured it might be Koolada after browsing through the forums. I'll tweak this I'm sure (still have 15 other flavors/additives to play with), but so far I'm liking this combo:
TFA Blueberry Wild (About 10%)
CAP Italian Lemon Sicily (little less, about 8%)
TFA Koolada (1-2%)
I didn't measure out everything well (used my syringe with mostly rubbed off markings), and I made a very tiny bit of this since it's my first time (5ml), so it may need more or less of each flavoring, but I like the combination. I'll have to try it again after I completely clean and rewick my RDA.
Put a piece of clear tape on your syringes. You won't lose the markings so long as the tape stays on.
