The reason I initially bought some was to cut other flavors with. I usually like a very mild flavor, can't stand overly strong or sickly sweet, which I find so often out there. So when I'm in a mellow mood, I mix a flavor with flavorless, 50/50 or so, and get just a hint of something-or-other wisping by, mostly on the exhale, as opposed to getting smacked upside the head. The only time I like something sweeter is after dinner, like a dessert vape. But for daytime vaping, I take it down a notch.
Same here. Most juices have too much flavor for me...so if I'm in the mood for a flavor I cut it at least 50%.
