I wanted to share this. This is the wick I now use on the Spheroid - 2 side by side loops of 1.5 ekowool and wire of choice(use a needle to stabilize wick and help wrap coil if needed).
The loops are pulled to size by tails and cut off. The loops lay in perfect angles to sit on the sides of the airtube in contact with the fluff and tend to stay in that
I think this is a better option than the figure 8 I was using because these loops will not disfigure or lay down. I can leave the loops 1-2mm longer than fig 8 or tails because these loops flatten easier against the fluff material and have more surface area to draw the juice from the fluff.
