Personally I would prefer less CO and more OO for less cleansing - but thats making soap to my taste and not yours. See how you like it
Yep. ^^ Everyone might be tempted to tweak it their way, but you should go with your own idea and see how you like it. There is nothing glaring whatsoever.
Your recipe looks good. I use at least 30% coconut oil in most of my recipes. It does not bother my family or friends, however some people find that much coconut oil to be drying. An 8%-10% superfat might offset that a little.
