I've been diying for a while now but just really unflavored which I use most of the time. I ordered some 12mg 60/40 from wizard labs to save me time from mixing the nic, pg, and vg manually. Cost wise it was about the same. Anyways I get a bit bored with unflavored at times and am interested in some super concentrates to play with. I know already it will drop the nic level a mg or two but that doesn't bother me. What percentage of super concentrated is usually adequate? 5 or 10 I'm hoping. Also which is the best place to order these for quality and price? I'm excited to give it a shot
