Actually, I just found a medium and fine Carborundum SiC stone in the sharpening box, so I think that range is covered. I've been getting a lot of practice in lately by sharpening my friends' knives for the holidays (partly because it is a kind gesture, partly because I hate cooking at their house with dull knives).
If you can get your hands on a old washita arkansas stone (not soft white) they are great for kitchen knives, hard to find these days.
Is the old washita one that looks slightly beige with specks that look darker beige? Or can you describe it?
