The thinnest option for a nic shot was 50 PG. We are coming close to a flavor ban in Estonia so there is not much to choose from since stock supplies seem to sell out quickly. I use a Cube mod with Tigon tank (1.6ohm coils 12watts). I could also just order some sub ohm coils for that juice, but I prefer the MTL ones better.
Sorry to hear the tobacco companies and your government are doing that to you.
In a pinch, a bit of vodka can be substituted for the distilled water to thin the juice down.
As the weather continues to warm up, you may find the thicker juices flow a bit better.
When adding distilled water or vodka, add by drops.
In a 60ml, I might start at 10-15 drops.
Shake it, let the bubbles dissipate and give it a try.
You can always add more salt to the soup. You can never remove too much.
The Tigon should handle the 70%VG, but may be prone to dry hits if you are chain vaping.
Again, with the summer coming you may notice the "thick" juice works just fine.
