Hey man I'll bump your thread, I'm looking for the same advice. I now have a ZMAX battery and a 30$ glass
tank (I probably got over charged) that fits cartos. Right now I got recommended the "
smok" tech cartos with one hole punch, not 2, and at 2.0 ohms resistance. I'll be testing these 5 cartos to see how long they will last, which is used up first my new 30 ml bottle of Peach flavor or the cartos. So these are pretty nice, I like them, but obviously if there is something better out there I'm interested. They also had boge cartos there, but I was recommended
smok tech ones. I think I'm going to make a new thread with this question in it along with all my other stuff I want to say, but I felt like bumping your thread anyway, its a good question I'm sure people can help.
