welcome Garey :wave:, I too am a CBA user. I am currently trying LX wicks- thinking of changing to them 'cause I like the way they self trim. I have always used RRD's. Try what you have and see if it works for you . As far as measuring....my method is probably way wrong, but it works for me-- I fill the jar I am going to use w/water, then dump it into a measuring cup. That is how much melted wax I need. As far as any "left overs"- I use empty plastic containers w/lids ( cottage cheese, margarine, yogurt. etc) I write on the top so I know what combination I have used it for. I re-use the same containers over and over again. I don't make any large sizes like you, 'cause people around here seem to only go for the small stuff.
