That's interesting, I wish that guy would have just told me that about the "drip line" being high in vg. I would have bought it for sure, because when I chain vape I want something smooth and cloudy which tends to be the high vg liquids I have.
Yeah, go for it; if anything it can be more flavorful if high-VG is your thing. These are usually 70-80%+ VG, and usually more flavor than you'd get by asking for their normal eliquid in a different ratio. It's sometimes more expensive, but that's just marketing.
Usually when you can specify what PG/VG ratio you want they are generally using the same amount of flavoring and adjusting the PG/VG in their calculator app, so if you liked their cinnamon flavor at 80/20 you might find it kind of weak and muted at 20/80. Flavor shots & such are a way around that, but not everyone does it and frankly it's confusing as hell to most people.
They compensate for the higher VG in their flavor ratio, plus extra due to people getting very airy draws from the new $70 uber-tanks and $300 mechanical mods they're pushing on soccer moms and freshmen who've seen youtubes of vapor chuckers, and want the RDA/RBA experience packaged up like an iPhone app.
Higher-nic levels not being in demand in shops like this is because like an RBA/RDA, nic hits *hard* when you're vaping 1ml of it in one pull, even if you're exhaling 75% of what you just vaped up.
