I preferred 70/30 PG/VG, and tried 80/20, since that was all one vendor had. I didn't like it. Not enough vapor. I came across another vendor that offered it and 65/35, and it's quite good. Having said that, it seems that i like somewhere between 70/30 and 65/35. I have not tried more VG other than 100%, but I really didn't like that much, so I'm sticking with the range I've had so far.
