Ok guys I'm fixing to buy a k100 but I don't know much about the cartomizers I should buy. I wanna keep the original shield cover so what's the best cartomizer I should get and for it to fit. I know I've been told to use a low ohms cartomizer. I also know I have to buy a drip tip as they don't come with them. I have a lavatube with a protank 2 but I work outside and my tank just leaks from the e liquid getting hot and leaking through the tube so that's why I wanna switch plus it's smaller. Is there anything else I should know that I need. I already have some batteries and charger but I open on suggestions if their are batteries out there that r any better than others.
