I have been struggling to find my correct PG/VG mix.
I have been using 30/70 and getting the tight/heavy chest. I figured the VG ratio was too much and so tonight I've been going with some 50/50 I had around. REALLY tight chest now so I'm thinking that the problem might be that I need to cut back even more on the PG.
Does this make sense?
I'm starting to get frustrated with this.
I'm not trying to sound like "Dr. Greenman" but have you tried 100% vg? You could have a sensitivity to the pg.
