I have had a better experience using 100% VG. I hadn't used 100% VG until trying Annette's sample that came with some hardware I bought from her. I have a cardboard box full of tank systems and cartomizers that I have gimmicked my way through. While being fun to play with in a novelty sense, I have found that the cartomizers with the filler material in them to be the most reliable. With VG I like bigger batteries and 3.5 ml cartomizers. All I use my variable voltage devices like the lavatube for now is dry burning coils. I use a simple, 1300mah device now because the longer battery life translates to a longer peak voltage curve, which keeps cartos at their optimum range longer. This is especially true when using dual coils, which when paired with 3.7 volts, gives me the best all around flavor and warmth/vapor with 100% VG. I wouldn't dream of ever trading this experience for analogs. I'm not even sure I care about the nicotine anymore.
