This is exactly why I say that a bad lather from Williams can out perform good lathers from some other soaps. Williams is still really slick even when the lather is not so good and can therefore still give a good shave. Some other soaps that I have used (*cough* Col. Conk *cough*) don't have enough slickness for me even when the lather is decent.
I agree about CC, I could never get a slick lather even with a good looking lather and I have soft water so that's not the issue. I just don't think CC is a very good soap.
