I have found wool to be a great wicking material for my RM2. I found pygmy sheep and have a flock that I rotate through. All thats needed is a small terrarium planted with grass to keep them in. I change out my sheep everyday. Its very important to keep keep them wet. I wouldn't want to hurt them or give them undue stress while enjoying my vape. If you are used to gurgling and popping sounds from attys then the occasional bleating that is heard is not really an issue. After all, its just a hobby. I think they vape as well if not better than cotton and its organic as well. Forget about threading them through though. The coil must be wound around rather than putting the wick through the coil. This example is using 32 gauge Kanthal, twisted, about 5 or 6 wraps ohming out about 1.7.
