I would avoid that 30/30/30/10 recipe like the plague. Sorry, Kiwimoose, but that is not a good recipe for a new soaper that is making soap for family and probably does not want to test for 6 months to find something for other people. It is fine for a new soaper that wants to be a soaper and test for months.
Definitely go with something like the recipe Shari listed, I would even give you more open parameters like:
45-65% lard, tallow, or palm
15-25% Olive oil, SAO, or other HO oils
10-15% CO or PKO
5% castor
Start at one end of the spectrum and change the amounts by 5% until you find your sweet spot.
