I read alot of that thread and yea it makes me wonder a bit, Ive yet to rebuild, still waiting on my order but I think ill be ordering some cotton soon hahaHere is that long thread i mentioned earlier in this topic. It goes into depth about different wicking materials and the safety of them, its a 290 pg thread i have not read thru it all yet but the medical gauze seems the best material. Its a long read but definately informative and IMO worth it.
