I've tried all kinds of straight vg and just can't find one I like. It's either thick or mixed with distilled water, the flavors are kinda muted, the watery ones pop as it burns, the thick ones gum up the coil. I prefer a mix, 50/50 or close to it. If you're gonna try straight vg, make sure to have a few spare coils on hand if you want to switch flavors.
