I've been using rolled cotton balls for a while now and love it over silica by far. The vapor output it easily twice that of silica in the same build and flavor is much better.
However I have noticed issues with it. Getting a consistent wick is nearly impossible, not because of varying amounts since I found a way to minimize that but because of the cotton itself. Fiber orientation is critical for good wicking and cotton ball fibers are all directions. The other thing hampering wick performance is the amount of pills in the cotton. These act like a dam significantly slowing juice flow. The only way I can get a good consistent wick is to comb the cotton and that's a lot of extra work.
I'm looking at rayon and ramie fiber but every source I find seems to be out of stock. Anyone know where to get raw cotton that's already combed to remove pills and tangled fibers?
