Been there done that myself. Turned out I was overpacking my cotton, once I figured that out I still wasn't happy with the flavor. I found that certain juices tasted like crap depending on the type of cotton ( I had a variety, organic, bleached, unbleached, straight out of the field, etc). I made the switch over to rayon and my flavor issues were solved completely. I've found rayon to be the best wick material I've ever used; I've rarely had a dry hit, easier to use once you get used to it and it doesn't affect the flavor at all. I've even ran it completely dry and refilled with no change in flavor. I even went back and dug out some of my "emergency" juices that tasted bad and found the flavor good on most, there were a couple that sucked regardless
