the way im mixing my own juices right now, i am liking a 33pg/66vg mix. i just count the drops as i am going starting with the VG. so if i start with 30 drops of VG, then i add 15 drops of PG and im getting good results with it. lots of vapor, lots of flavor, and a decent amount of TH just enough to let me know there is something there.
my VG is 24mg nic, so my nic level is about 15% after adding the few drops of flavoring needed.
