Thanks for the comments and suggestion. A difference is that I don't vape unflavored, and don't intend to ever vape it (I've tried it, not my thing). Vaping to me is all about the mechanics of smoking that I have enjoyed since I was 13, but I replace the negatives of smoking and nicotine with flavor. So it's all about the mechanics and flavor to me. I never have and doubt I ever would dilute my liquids that are all VG except those where the flavors are store bought PG based. When I extract my own flavors I use VG. So the intense liquids I use I probably wouldn't vape at all if they were not intense. For example, some of my DIY-NEF coffee's would probably jump start a mule that has been dead for decades. But then I have drank coffee for 60+ years, most of those years strong black coffee. In general I can't gag down a lot of the flavors that many folks thrive on for vaping... fruits, bakery, desserts, cereal, candy, etc. Certain fruits are a staple in the mostly raw food diet I devised and changed to about 4 years ago, so I eat very little bakery or desserts, no cereal or candy. My vaping preferences are mainly beverage (coffee, tea, liquor), nut & spice flavors and a little tobacco now and then.
