About the only thing that works well with 100% VG is a dripper, other than that try thinning your juice with distilled water, it doesn't take much water to thin VG try a couple of drops per ml. Don't use tap water it contains chemicals that cities put in it like chlorine, and other nasty stuff. If you are using a citrus flavor you can use lemon juice instead of water. 
If you use a plastic tank don't use lemon juice for a thinner.

There are several flavors that are considered "tank crackers," such as menthol, cinnamon, and some citrus flavors. Most vendors will make this very apparent when you buy juice from them, others print it on the bottle.

Celtic vapour do a 70/30 vg/pg mix and have a great taste, they do a 0mg, 5mg, 10mg etc, not usually available in the shops in that combination....the shops do a 50/50 mix, but I have seen it on their web site. It's based in Swansea, south Wales. Hope this helps.
