32 is the magic number when it comes to building
coils for ecigs. You can use it for standard resistance, but can still get low resistance with fewer wraps.
SS rope seems to work well with genesis atomizers. I have some, but have yet to start experimenting with it. From what I have read, you still need something to wrap around the SS rope where the coil is built. Some use SS Mesh, but you could use Ekowool or a silica sleeve. You should be safe if you order your SS rope from a
vaping site, ala Kidney Puncher. If you order from ebay or Amazon, make sure your SS rope is not galvanized and make sure it does not have nylon inside of it.
