xCjack, this thread is filled with terrible responses. You can use 100% VG, like from Velvet Cloud Vapor, without issue. I used to use it in Kanger Protanks all the time, never had difficulty. An eGo battery and a bottom coil clearomizer, like Kanger Evod or T3 will work fine. I absolutely love Velvet Cloud Vapor and pretty much only use Night Shift or Vanilla Custard from them now. Their White Beard tobacco is good too.
People who say all VG juice does not have flavor or is too thick are people who have never used VG juice a lot. It is not too thick and has tons of flavor. The only thing I would caution you is to buy 100% VG juice from vendors that really specialize in it. From the top of my head, I would say Velvet Cloud Vapor, Heathers Heavenly Vapes, and Alien Vision are good vendors that can really make a VG juice well.
Do not listen to the negative responses above. They are opinions and IMO very mistaken opinions. You do not have to use PG in a juice to have flavor or make it less viscous. That is simply not true
