I find that if I use a 50% VG / 50% PG mix produces a good cloud of vapor. You just need to make 100% sure that the VG has been pre watered down with H2O to a (85% / 15%) mix before carrying on. It wicks fine and I don't have a problem with getting enough through. It vapes fantastically and gives a nice sweet taste. It is quite low on the throat hit so I would stay away if you like a good throat hit.
It does burn through the liquid at a higher rate with this mix but I can fill a room to the same extent as a smoke machine
. Well worth a try to see what you think of it.
I use 50/50 and I can block the sun with my clouds of vapor. I only watere down VG 5% because the 50% PG makes it just the right viscosity in the end. Like you say the hit is very small with this mix. I get my hit from my flavorings. I use the eGo-C and no problems at all, no burnt taste and no leaking.
