So I was looking at the 2 side holes in the updated Subtank rba deck and thought to myself, why not treat it as a clearomizer instead of just another build deck? Thread the cotton through the first hole, then the coil and out the other hole. Cut the cotton so that about 2mm of it protrudes out of the deck and see what happens. This way the cotton fibres are nicely lined up and the distance to the coil is minimized. As it turns out, this is the perfect way to wick the rba deck. No dry-hits, spitting or leaking. And this is with a 70/30 blend.
