I'm not a candlemaker by far, but when I do make them, I use the 4630 from Candlescience. Top of my head I can't remember what wick I use, but I get a great hot throw from this wax. To find the correct wick, I used the tool on candlescience's website. Have you checked to make sure you're using the correct wick? I'm sure this isn't a help, but just a thought! Good luck!!
