With no disrespect intended toward Anthony, I no longer accept the assertion that PG conveys flavor better than VG. Numerous posters I respect on the DIY forums have challenged that assumption as well.
I agree that VG produces more/thicker vapor, but I don't find VG an "inferior" carrier for flavor. Flavorings do take longer to distribute or dissolve into VG than PG. The overall vaping experience of VG versus PG may be slightly different, but that's due, I think, to other characteristics of each base liquid, such as viscosity, rather than ability to convey flavor, per se.
YMMV, of course.
From what I've found the extracted flavorings from VG are just as good as the PG ones. It's when the flavoring is PG based that it will be lost in a VG dominant liquid. I've tried three cigars flavors extracted from VG which were just as good as any PG version.
