I currently use 70/30 VG/PG ratio and this is why:
Please remember, this is my opinion and might not be the same for others.
Firstly to remember about pg:
GOOD TRAITS PG:
Absorbs faster
More throat hit
Holds nic and flavour
Longer storage time
Lower power needed
BAD TRAITS PG:
Thinner
Less...
We have decided to change our VG/PG ratio from 50/50 to 70/30 in favor of VG.
This will of course result in denser clouds :D while at the same time reduce the throat hit a little. But the result will be a much smoother vape especially on the sub ohm tanks and stronger batteries that is so...
