I would say more PG = more flavor more VG = More vapor, if you dont have your right nic level in your juice you wont get your nic Level satisfied and then you will be continuously
vaping wondering why youre not feeling right, that is if you have quite analogs recently. However no Nic will taste good as for just the flavor but the juice companies adjust the flavor to the Nic count when mixing I would think, also a lot of times when I order something from a vendor I ask for double flavor, try that, I mix most of my own juices and like a big flavor and usually mix about a 30%-35% flavor but it also depends upon the flavor too. Hope that helps you some what
