The Large slope trades a little bit of the depth of the Large Pro for a touch more space in the shell and can carry 2 bodies, 4 lenses and a few accessories. When storing a long lens (70-200mm/100-400mm) across the width of the top of the ICU, it wastes a large amount of the depth. With the slope, this is much better utilised by offering that space for storage in the shell 'behind' the ICU. The Large Slope ICU can be paired with the Ajna, Tilopa or Lotus shells, depending on how much extra space you want.
