VG is a humectant too IIRC. Whether or not its "drying factor" is weaker than PG, I don't know. Most of my DIY kit is finally here so I have been playing around today. I made a 25mg, 75/25 PG/VG base, counting on flavors being mostly PG and thinking I will like 80/20.
I think I like this mix fine, but might try more towards 70/30 or 60/40. Some pre-mixed juice I had said they were 70/30 but were way more goopy than what I made. I think that could be because they had some sort of sugary caramel though.
Something makes me not want to dilute VG with water. Have you tried Triacetin yet Kurt? I got one oz. but haven't messed with it yet.
Oh yeah... I tried ~90% VG due to having no PG besides flavorings this weekend and hated it. It was clearly coating my tongue/mouth/etc. and giving me phlegm. I can see why people say it mutes flavors, which might still be a good thing in some cases. I am curious if anyone has tried a minimal amount of VG to get plumes of smoke, since I read that 100% PG has almost no vapor. The smoke I got with near 100% VG wasn't anything special to me, just hung around a little longer, not enough reason to go heavy on it to me.
