Best juice ratio for TC

[Paul lamb]

Hi

Yesterday I got my new TC mod and tank with NI coils, I was using 100vg in it all day yesterday it was amazing, today I am starting to get dry hits at the same set points? What's going on? Is the juice to thick? I have changed the flavour of the juice but nothing else?

So guys what ratio do you use when TC mode? I like to have big clouds which is why I use VG, any thoughts
