Thanks for your reply. I have a Siren mtl tank and I build my own coils but never have I thought there would be enough 'hit' using a 70/30. I vape 12mg on mtl and I've had a cheeky try using a 70/30 before but the liquid just seems to be too thick? Am I missing a trick here? I build coils at about 0.80 roughly. I have a beaut popcorn dtl juice but it's 70/30 that equates to a 12mg 'hit'. Forgive me, I'm not a useless when it comes to juices ratios and such. All I know is that I am a 12mg mtl girl and if I can equate that to juices made up for dtl but can be used for mtl, I'm willing to learn!
