Though I vape unflavored most of the time, I still do drip and sub-ohm flavored liquids, before this stage I was mainly a flavor chaser in all my devices, before that I was a cloud chaser and before that I was an intermediate tootle puffer, and before that I was a newb beginner. Been vaping 3yrs or so, pretty broad in my experience, not beating my own drum, but have enough experience I can at least guide or nudge someone in a direction to look at, every vaper is unique as is every builder is unique in their own styles of vaping and building. I've been there and continue to delve into the area of mid-tier flavor chasing sub-ohm and plus ohm vaping, how I know one of my builds is spot on and will be good for flavored liquids, yes it is a just straight 100% VG 0mg I prime and test with, if I can clearly taste the sweet taste of just VG, ooooh boy, that wild berry mix or melon blast flavored liquid I will be using is going to be, "Mmmm, mmmm, mmmm...yesssir that the sweet spot O_O."
