I have a bottle of Blueberry, 100% VG from Northwest Vapors. Its 24mg, so it hits like a champ. At 3.2 - 3.7V I find myself more than satisfied with the throat hit. Like everyone else said, the higher nicotine helps.
This is by far my favourite juice at the moment, but given the fact that its 24mg and I direct drip onto a LR 306, it probably took a lot to get this guy to punch me in the throat like it does.
