That's what I was thinking. Dual coil works well in an Odysseus because you stack them on top of each other but this configuration seems odd.

I was able to center the coils directly over the airhole - the dual coil is sorta similar to having one giant coil wrapped around a super fat wick. It's a bit tricky to set up, but has vaped very well, but not sure I see any benefit versus a standard setup. I'll full around with it a bit and see if I can get it to work better.
Definitely an important part of setting up the Kayfun is wick placement as well as how much wick--too much wick and it'll choke or flood, to little will also flood. I'm finding it's easier to setup the mini kayfun, and vape production and flavor is just as good or better than it's big brother. In addition, the mini's are pocket friendly, so it easy to take to work, etc.
Here is the youtube vid on how to set up the dual. He seems to be getting excellent vape production with his setup.
