I found that wicking from both ends of the coil greatly reduced the process causing coil deformity. Cut the wick in half lengthwise and twist the ends of both pieces so it can be easily threaded. Then insert the pointy end of each piece in opposite ends of the coil. Very gently pull the wicking through simultaneously with equal amounts of pressure for both pieces.

I just put a random number of wraps around a 3mm coil, and it came out at .13ohms. Heated the coil to 550F and pinched with ceramic tweezers, and it looked pretty good. The biggest problem was getting the cotton in, as the coil easy got deformed. Next time I might take the coil out before I thread it, because it isn't that much room on the Rose.

Most people are using either 28 or 30 gauge so both sizes are worth trying. If you want to play around with twisted wire you might want to pick up some 32 and/or even 34 gauge. Mamu posted a photo of her genny build using twisted 34 gauge.Quick question. I just ordered a VS 40 and am not sure what size Ni200 to get (30 gauge, 28 gauge?) I consistently use my Svoemesto Kayfun Lite v2+, but am also planning on getting an RDA and building it with dual coils just to play around with. Which gauge would be best? And does VS include any Ni200 with purchase, or should I order it before it gets here?
VS doesn't include any free wire with the rDNA40. They sell some separately but you can get it cheaper at Lightning Vapes.
