i'm not too sure if i'm remembering correctly (honestly it could have been another vendor but i've never visited any other vendor juice sub forums) but if i am, it was something like 8-10% flavoring for the juices. and recently, when i convinced a couple to switch that i'm friendly with, she said, "get me as high vg as you can".
for whatever reason, i phoned in that order, and talked to Geoff. his response to that request (i only asked for 40%) was something along the lines of - i'll try to get it as close to 40 as i can.
but that was at 12mg...
last time i looked at the doublers (until just now it was late last year or early this year) the max vg was 70%.. which its now been dropped to 50%
which if memory serves, is what i've seen bmwjens posts rave about, with the addition of a small amount of 100mg nic juice to 6mg
ETA: thats a good picture of 'House'

I'm british, so i feel silly for not remembering his name, but i love the avatar
