I run mine at .3 which is the lowest you can run it. a build of .4 dual coil will suffice, not a cloud blaster, but build more for flavor and you will be all right. A Patriot v2 or a Tugboat V2 is a good atty to run.
Ed: I have an Ego one Mega, not the smaller one. The mod will not fire below it's safe theshold, so you are safe. The ego one is a semi-mech, meaning it has a digital switch and protection for shorts and below safe limits for the battery.
