Right now I use nautilus minis and aerotanks on my ISticks and build around 1.8 on my REOs. Most of my juices are a combo on pg/vg. Wherever the NT juices are so they vary. I have mixed my 12 mg with 6 mg as I am working my way down to 3 mg! I am also trying to trade for some Gravity, Raz Cup and Betelgeuse so I can mix some of my higher dk with ND! I am trying to be creative!Yeah you can but it will start muting the flavor. You will be altering the flavor to pg/vg ratio. I assume your a high vg right now??? What tank are you usingn
