Quite agree with what
@Crewella has said.
Many people use 60vg 40pg in MTL tanks with stock coils.
You can get away with 70vg 30pg in some tanks, but that's about the max.
I vape somewhere in between MTL & DTL, so have several stock coil tanks, and RDA's, RDTA's.
As I mix some of my own juices I have tried several mixes for my stock coil tanks using aqueous glycerine, with either 10% or 20% water in the AVG.
Also using VG with distilled water added into a mix (note, if this is done on a long term basis you need to buy Pharma Grade DW, not just everyday DW from Halfords)
Mixing like this opens up all sorts of opportunities, you can end up with juice that is as thick, or thin as you want, keep PG levels down if you are allergic, and if you don't like PG, but miss the "throat hit of high VG mix in some Vodka instead of DW, and it will increase the "throat hit".
