Theres so much on this. You have to scan the forums... ask the vets etc...
Basically, it is commonly believed that PG gives better
throat hit and flavor while VG gives greater vapor. Most juices are a blend.
But really, it comes down to a personal preference.
I prefer VG.
I notice the increase in vapor. I prefer the flavor...
and I have no problem with
throat hit whatsoever...
Just
buy some of both and get a blend.
It's really a preference thing unless you have a PG allergy.
Hopefully someone can post a link to the wealth of info...
I'm tired and gotta hit the hay ;-)
