I don't much care for silicon carbide for a precision hone, they are always very friable in my experience. India is far less prone to letting go of grit. But I have not used Tyrolit.
Sorry I can't be more help with grit and hardness, the thing is, once you flatten out several good "precision" hones, you don't really ever need to replace them. They don't really wear much. Sort of a lifetime gig once you have some good ones. Even the ones I use for rougher work can last quite some years.
You don't want to be using these for any kind of work where there's point contact. Keep it to large surface area contact and they last forever.
