Natty, Are you finished testing this one yet? I went on a wick hunt...actually organized all my wicks, again, and found some 60c's so I tried it, like Henryk suggested. It got a big shroom on the first burn but almost made it to the sides in about 2 hours. I trimmed and it's doing great. Even if it shrooms up each time, it's not leaving the mess in the wax I was getting with the LX 26. I have never yet had a wick catch up on the sides after it's 1/2 way down in a container this size, maybe in a smaller container it would. I feel like I'm cheating my customer if the entire candle burns leaving 1/8 - 1/4" of wax on the sides. I'm convinced after I use up these cases, I'm not buying these containers again.
