I've had the pleasure of owning an iAtty, Ody's, and an Ithaka, I've had some experience with build up on the coil. tobacco flavors w/menthol are my favorites. I've rebuilt them as often as once a day, dry burned them, just changed the wick and reused the coil. So building coils has become a minor problem to make time for.
I have noticed the larger the wick is in the coil area itself, not in the channels, the better the wicking, it stands up to dry burning better, and lasts longer.
With my Ody 1 ohm, 28 or 30 game R wire has been my preferred coil on approximately 6 mm of wick. The Ithaka is still to new and I haven't experimented enough with it to respond yet on my favorite most efficient coil and wick.
From my experience I would suggest more wick in the coil region, and less or none in the wire channels. Due to the loose positive wires on the Ithaka be careful not using any wick in the channels. However having no wick in the channels works very, very well.
I use 2 18350's when I dry burn a coil. By just powering up the coil for short periods and taking my time cleaning the coil and wick once a day, they both seem to clean up nicely and continue to perform.
