Hi Aarik.
I vape all vg almost exclusively about 2-3ml per day. You're right, Cignot's Basic and ECOpure lines are excellent but the selection is limited. Right now I'm getting most of my vg juice from DIY FlavorShack. She is putting together a line of vg based juices. In addition, I vape pure USP vg from the drugstore w/ a drop of vg based menthol per ml and I get a nice clean, 0 nic vape which I find very relaxing.
vg clogging atties, imo is a MYTH. I've never had a clogged atty, and I haven't seen any all vg user say this (I see the opposite)...this "advice" is usually from people who don't vape all vg (who probably heard it somewhere)...and it gets perpetuated. Please, if I'm wrong, someone correct me on this, but that's been my experience and observation.
I believe what clogs atties are the ingredients in juices (extracts, dyes, sweeteners, etc.), and not so much the base, whether its vg, pg, or pg/vg. On the rare occasion that I feel like cleaning my atties (seldom), vg seems to rinse out well with hot tap water, and I never dry them.
Just my 2 nickels Aarik and I hope it helps.
