Leslee42 Thank you for the information- I was just using Eco wicks in straight 464 per CS wick recommendation but after alot of research on 464 users I did order CD wicks to try- I use the 8oz. square mason jars for candles and have always used the max fragrance load-12% but maybe that is too much oil for this wax and contributing to my burn problems, but that wouldnt explain why my tarts are weak- so frustrating! Thank you for the site for CD wicks- they are not easy to find without buying in 100 plus. Also you say you use Peak? I tried a few of them and they seemed real weak, if you dont mind sharing the ones you have had success with in the 464? Thanks so much
