I don't know if this has come up in discussion before
, and maybe there's a reason i shouldn't be doing it; but has anyone else tried replacing the polyester material inside their cartridge with jute/hemp rope? I'm using a 1/4" natural, untreated variety I picked up at Joann Fabrics in my NCig~RN4072. It wicks _really_ well and has pretty good capacity/absorption and I'm no longer coughing up a lung from the melted plastic flavor. Are there problems or hazards I'm not aware of with the rope?
