I'm trying them myself and was wondering if you have any other that you recommend (meaning WC from other software) I'm trying to work around it and tweak them to make them good for me in CSP... this said I know some people use other apps that make wc look really good

I've been using corel painter and its digital watercolor for a long time. and its new real watercolor, while slow, does a good simulation of edge drying. I think painter is abandoned now, alas.
