My favorite set up for the Kayfun Lite: Micro coil using 11 wraps of 28ga kanthal around a 1/16 drill bit. It comes out to 1.3Ω. The wick is simply a piece of sterile cotton, from just the cotton balls you can get at the drug store. Just size the piece of cotton so that it threads easily through the coil, which is already mounted.
I've built figure eights with ekowool and silica; and I prefer the micro coil/cotton set up. JMO
