Which cartomizer do I need?

[Mickyvap]

I would like to try a cartomizer, which one do I need for a standard 510 with standard battery?

2.5 ohm is the standard and you can go down to 2.0 with a regular battery but the lower you go the shorter the battery life.. Below 2.0 ohms has a higher risk of taking out the battery.
