I've used WSP's and I like it best. I haven't used a CP stabilizer with it but I have tried the stabilizer with Vanilla Bean Noel. It turned a funky pinkish brown color over time. Ugly! Ugly! Of course, VBN has a higher % of vanilla so it may work with the DB.
I'd be interested in hearing if stabilizer does work because I'd like to try some colors in DB soap.
I saw that! ~ Karma
