Hot Liquid on Tongue

[livingword26]

I'm using a smoktek 65o mah ego battery. I have 2 different kinds of clearomizers, a Vision Ego V2, and a similar one, which is a smoktek brand, or an off brand. When I am drawing normally on them, I have no problems. I discovered, however, that if I draw slowy, I get a better hit. If I do this several times in a row. I get some gurgling in the clearomizers, and an occasional drop of hot liquid on my tongue. You would think that the harder draw would be more likely to pull liquid through, but I am wondering that if the slower draw is heating things up enough, that the liquid is becoming less thick, and getting pulled through faster. If the latter is true, then it seems like a VV battery, set at a higher voltage, would cause the same problems. Any idea's?
