Recently I had my first purchase of ATF and I got it all PG. Now I'm realizing it produces almost no vapor, but really a lot of flavor. My question is how much % VG do you use to get a good amount of vapor, but without loosing the awesome taste of atomic fire ball. I've tried 100% vg carts and they have no flavor but awesome vapor but I don't want to order and have too much VG, just enough to get more vapor. any advice
