The tobacco flavors are coming through nicely for me at 2.5% - 3%. I'm mixing 50/50 pg/vg for all my diy batches. However, I have two fruits that are not shining at that ratio. Peach and banana seem a lil weak at that ratio, and even at 4% I dont' seem to get that "juicy peach" I hear about. Maybe its my taste buds, but I'm wondering what ratios some of you are using for the fruit concentrates from VZ.
