working with the ISRIC 250 m African soil grids

I'm preparing to run the InVEST sediment and water yield models in Rwanda and want to use the new 250 m ISRIC African soils data (http://www.isric.org/content/african-soilgrids-250m-geotiffs) for the needed PAWC and soil erodibility inputs.
Problem is, the inputs are available at multiple depths (2.5, 10, 22.5, 45, 80, 150) and AWC is available at different field capacities (pF 2.0, 2.3, 2.5). Which depths would you recommend using for developing the k factor layer for soil erodiblity and which depths and field capacities would you recommend for calculating the PAWC layer?
Since there are no redistribution restrictions on the data I'm happy to share any derived products for others' use elsewhere in Africa.

I want to run InVEST models (sediment retention model and nutrient retention) but whenever i try to download INVEST setup ,I cant see the interface for both models.
thanks

I think the input datasets for my water yield is not large, let me attach a screenshot and take a look or you may give me your
email so Ican drop my inputs
