Recently Ive been doing a pancake sort of wick.
Just enough wick on each side to touch the holes, fluff them out into flat pancakes and place the rba sleeve over, ensuring the holes are blocked with fluffy cotton. I do this by poking the wee blue screwdriver around the corners near the post screws as no cotton is needed in those corners.
Also I'm using cotton bacon which is very absorbant.
Any questions let us know, hope this helps!
