You still using 28 ga. Kwalka? I am, and it's perfect, but I don't get more than a day or two out of a coil before it's too gummed up and starts declining in performance (Using 50/50 PG/VG Copper Creek House Blend). I've tried cleaning one still intact, but it doesn't really get back to 100%, and isn't much easier than just rebuilding it altogether.
I rebuilt both of mine yesterday too, but certainly will again before the Ithaka. I'm hoping that perhaps dual 2Ω coils will last longer than a single 1Ω...
ETA: Working on the assumption that you aren't actually going to stop stalking this thread and will see this.
