As I'm just into my 4th month of vaping, I'm beginning to taste more and notice more things that I didn't notice before. I have pretty much consistently been vaping a 50/50 blend on all of my flavors. I am just now noticing a kind of a greasy aftertaste that is really bugging me. I'm also noticing a muting of flavors. I'm wondering if changing to a higher PG level would fix this, say 65/35. Anyone else experience this? It's like how your mouth feels after eating a greasy cheeseburger...not great. I would still like to get good vapor so don't really want to go to an 80/20, which I know is standard for many vendors.
