That is a awesome coil for a first time - congrats. On the Kayfun it is should rotate 45 to 90 degrees from where you have it, makes wicking easier as well. The secret with cotton is not too much. The ID looks thick enough for me.
OMG that makes so much sense now you say it! It will be a lot easier to position and fit as well! Let me suck the Kayfun dry and will make another coil and wick a bit later... I'm actually getting better flavour now and it is comparing to the Nautilus pretty well and I'm sure when I get the coil positioned with a decent wick I can only imagine the improvement!
Thanks @Matthee!
