When I used 4627 straight, I had the best luck with zinc wicks... the scent throw was great but the mushrooming was horrid. I know that zinc wicks are not usually recommended for this wax, but I tried so many wicks and always went back to the zincs. At the time, I lived in a humid state with lots of rain... now I am starting testing in the desert. LOL, I know it sounds silly, but it seems to me that the wax, fo, and wicks are reacting differently here. Sorry I couldn't help with your particular wick... :/
