I am thinking of getting either the x-coarse/coarse or coarse/fine DMT Durosharp stones for lapping my hones.

My hones consist of Norton 220/1K, 4K/8K combo stones, Belgian blue, Coticule, Naniwa 12K and a couple other finishing stones.

Which would be more useful? I am leaning towards the coarse/fine comb but wanted to see what others thought.
