Start simple. Get some 28 gauge kanthal and build a single coil 6-7 wraps. That should get you around 1.4 ohms which seems to be the sweet spot for Kayfuns. I've never even burned out a coil, just changed it when the resistance seemed to be climbing. A coil will likely last a couple of months. When you get some practice and feel adventurous, try some of the more complicated
coils. However, you'll probably need a different
tank.
