See I disagree... with HPing, I found that the bars were MUCH harder after a week or two. With CP I found that my soap was slightly "sticky" feeling for at least 4-5 months after I made it and I didn't have that feeling from HPing. I think I will HP my castille recipe from now on... it worked out great!! I have only done one batch like this, but those were the immediate differences, I really felt that it cut down on that long cure time.
