Sure thing. The list has probably even grown since we discussed it!
1. Even from a relatively light amount of research, it seems pretty clear that VG is a better "carrier" for alkaloids. This seems true also in my experience with both VG only and 70/30 PG/VG.
2. VG does not "go bad" and PG does. That's huge for both us and customers.
3. Though some people do have allergic reactions to VG, the number of people either allergic or sensitive to PG seems much higher...fairly common, in fact. We'd like our e-liquid to please the largest amount of people possible.
4. PG, in my understanding, is normally a constituent of e-liquid due to its ability to deliver a strong "throat hit" and well...as you all know by experience, that isn't necessary with WTA.
5. I do have some PG, but I am seriously too busy at this time to mix special batches. That's unlikely to change any time soon. Sorry about that.
6. The VG we use is mixed with distilled water at 7%...it doesn't take much to change viscosity. Another 1 or 2 percent should do the trick, without much of a change in how it vapes. That's what you probably want to do, flowerpots.
Hopefully that covers it!
