I am testing Taylored concepts container blend with a 7oz Status Rock jar. These jars are straight sided and have an opening of about 3.5 inches. I have tried a 51z, 60z and 62z. The 51 was too cool and the 60 and 62 were too hot. I also tried double wicking with a 36z, which seems to burn too fast. I do have sample packs of the Cotton and HTP wicks, but I have very little experience with them, so if someone feels that they would work better could you give me a starting point? I have NEVER had a problem with wicking like I am having now and its getting very frustrating! TIA-Mashala
