I'm a new vaper (<--right click, add to dictionary

) and have been having some throat problems as well. In my case the juice is 80% PG and almost impossible for me to get down. I have another juice that's 65% PG and it's doable, but still uncomfortable. I've concluded that I don't tolerate PG very well and I would suggest you might have the same problem, but you say you have no problems vaping your juice in your tank on your friend's ego. That's pretty puzzling to me... can anyone weigh in on why that might be?
And if I may sneak in some barely on topic noob questions...
My next order from Mt. Baker will probably be either 70% VG / 30% H20 or "Max VG". Is Max VG 100%? Is there some downside to having H20 in your juice? Does it dilute the flavor or thin out the clouds? What kind of atomizer is advisable for vaping 100% VG? I'm using an iclear 30.
