I just built and juiced my new Zeus Dual. The coils came out nicely, if I do say so myself, but I must've gotten the wicking wrong because it's dry-hitting like nothing I've ever experienced before at a lowly 50W. *cough* *gag* The coils are 2.5mm, six turns of 24 ga., coming out to 0.22 ohms for the pair. They lit properly & evenly when I tested them before wicking. I wonder if it was this RTA one of the reviewers noted it was vitally important not to over-stuff the juice wells? That the cotton should not reach the bottoms? If so: I may have over-stuffed them. They didn't seem over-stuffed, but maybe they are.
