No, have not tried the ekowool, yet. However, I am planning on experimenting with some 3mm loosely woven Germany silica and some cotton yarn.

I've been using the 3mm German silica in various rba builds, and it's hand's-down the best silica I've used. (Especially regarding flavor)
The e-bay seller stated the following info about the fiber diameter:
The fibers have a diameter of exceeding 6 micron and therefore they are considered as harmless to health.
I ordered a Diver today, and am really looking forward to giving it a whirl...
