I'm interested in trying a map tank mod. The problem is I know nothing about them other than the fact that they hold more juice. Are there any other advantages to using this? Lastly, I don't know which one to buy. I will be using this on a GLV-2 Super Mini 3.7 Volt Electronic Cigarette with One CR123A Li-Ion Battery and a 510 connection. I see there are different OHM models. Which one would be the best for this Mod with the battery I'm using. I see Clouds of Vapor sells them.....is that where I should buy it?
