Been vaping with vivi novas these few months and been enjoying them so far. But I want to try cartomizers out, but dont know where to start. I believe there are two ways of using them with the tank or without the tank(dripping???). Anyhow I just need some help choosing out some to try. I'll be order some batteries(for vamo) from crystal clear vaping soon so if any are good there then ill add it to my order since its free shipping. I also like to vape higher resistance 2.5-3.0 if that helps.
