I think the ipv is probably the way I will go. While I don't post very much, I do follow the forum enough to know both you and tug are two people whos vaping opinion I respect and pretty much take for being the best advice someone could ask for. If you both say ipv that is good enough for me. now to pick batterys. what is your opinion on those. I do know to keep the pair married and label etc but what is your pick for best battery for this mod. on another note do you recommend a certain battery charger
