I'm at 6mg.
Even with a 100% VG juice, I found it difficult to do lung hits with 6mg nic. I had to go down to 3mg before I could comfortably lung hit on the Magma fully open with dual 3mm holes. 6mg and higher would choke me up..
Heathers does offer 100%VG with their juices in the Purity Line and some of their fruit and dessert offerings are much loved here.
