VG does give more vapor but I say it dulls the flavor more than PG and reduces throat hit ... PG hold flavor better its thinner and produces less vapor .. so when using heavy VG it will sometimes have a time soaking into your wicking ... I use 50/50 ... sometimes I use 65%PG/35%VG
Either of those above produce clouds of vapor, so it depends on what you like better, try a few of the same flavors in a few different combo's would be my opinion to see what you like better, then run with it, but still knowing different flavors still can act differently in the future when deciding on percentages of PG and VG
Using a variable volt device really makes a huge difference in all this, dialing it up for a warmer vapor can give more hit than say a cool vapor (my opinion), I am using a Provari V2.5 and a Vamo V2 and "Vision" branded Vivi Nova
