I just started mixing and do not have any vg, just pg, so my setup is 100 % pg. I've not noticed any adverse effects of pg. With that said, I think that I will get some vg and try a batch of the same flavor to see how it's different. Does anyone know the ratio that Spokane Super Sauce uses? I was happy with that sauce, it came in marlboro flavor, not sure of the nicotine content.
