Schiz - I have a collection of low, medium and regular resistance cartos if you want to give them a try. Also some blank medium resistance 901 cartos (Vapor4Life premium) cartos. PM me if interested, only warning is do not juice all the way up only to find you don't like cause they take a lot. Are you ego and a 5V? The cartos supposedly are really good on a 5V, shouldn't use the lower resistance on the 5V, harsh and you'll pop em. Let me know, I have no use for them and am hitting the PO tomorrow.
