I too purchased those jars. I only had time to make and test one, which didn't do well. I started with a 60z (all I had on hand was 44z, 52z, and 60z) and that wick was way too small. I haven't yet had to time to play with them anymore and I am waiting for my wick sampler pack to come in. I will post should I find a wick that does well.
