I don't know what wax they use nor have I burned a WW candle of theirs but I have been testing the wood wicks from C&S in my soy candles. Pros: 1) The hot scent throw is MUCH better with the wood wicks than with my usual HTP wicks. 2) I get a full melt pool much quicker and the depth is consistent no matter how long the candle has been burning. 3) The sound of the wood wick is really soothing in a quiet room. Cons: 1) The wicks are really hard to keep trimmed to the right height. My first burns are perfect but once I re-light I'm finding that it's a 50/50 shot of the wicks staying lit. 2) Very inconsistent from wick to wick. I trimmed all wicks to the exact same height and found that the flame height on each wick was very different. Strangely, this didn't affect the burn of the candle at all. 3) You can't hear the sound the wick makes unless it is very quiet or you get right on top of the candle. I'll use the wicks for my own enjoyment but I can't see the normal consumer having much luck with the wood wick candles. This is JMO as a result of my own testing but I do wish you luck and hope your testing proves successful.
