So I am looking at building my first rebuildable and I was really looking at the dual coil 3 post RBAs. I only have a KGO Variable Voltage battery for the time being and was wondering if you guys (and gals) recommend using a dual coil over a single on that. I will still probably get a 3 post cause I know I can do either with it leaving it open for future options but my question really boils down to if I was to go dual coil what gauge Kanthal should I use to get the right amount of ohms and what would the right amount of ohms be for that battery?
