Soap is a surfactant by nature, so soap made from any oil or any combo of oils will get you sufficiently clean.....even a soap that SoapCalc states has zero % cleansing, such as a soap made with 100% olive oil, as Anstarx pointed out above^^^.
The question then becomes, "How much of the cleansing effect can your skin tolerate?" And a related factor is "What kind of lather do you prefer your soap to have, e.g. creamy or bubbly or a nice mix of creamy/bubbly?" When formulating a new recipe, those are the two factors I'm always playing against each other. I'm a bubbly lather lover, so my formula includes a goodly amount of the bubbly oils of coconut oil and/or PKO, which also happen to be super cleansing oils, so I formulate in such a way as to have enough bubbles to make me happy, but not so much cleansing that it drys my skin out. It's a delicate balancing act for sure.

Edited to add, I like using a combo of lard with tallow....I find they compliment each other nicely.
