If you increase the PG, it carries flavor better, but especially bitter flavors. So the flavor will change some but the total taste could increase. I currently use Puffcake diluted, between wanting to reduce flavor and increasing PG from 30/70 to 50/50 I'm using approx. 1 part ejuice, 6 parts dilutant. I don't like the flavor as much, but there's plenty of it.
That’s actually bringing up a question I just realised regarding juice flavours. Using TFA flavours like blackcurrant or gummy bear has been a really bad experience as my original idea was that pg was bad for flavouring so I would run at 70/30 VG/PG to (what I would assume) would smooth out the harshness caused by the PG. then when I tried out the 0mg Nic flavours they were at 65/55 VG/PG and smooth as butter.
So one of the things I was told was that sweetener makes
I seldom use sweetener and most of my juices have little if any th. I mix max vg/dw 6%,my only pg comes from flavors. My flavor percentage runs from 15-5%. I also mix with nic salts to reduce th. I would guess that some sweetener or EM would smooth some, but pg is the most likely culprit and of course nic quality.
Yes the nic quality is one issue I will need to address soon and I’m pretty sure will be a big factor, I got a bottle of HiLiq from an acquaintance and it was already yellowing so be looking to get some fresh stuff in the near future (cost etc). You mentioned “th”....what is that?
