I very much like the idea of these stones, (the stones you offer) but how often do you have to lap them flat?
That depends on how often you're using them, what one, and how good you are at spreading out wear across the face of the stone. But they're fairly hard-bond stones meant to be used with firm pressure so they don't wear out of shape easily even under the worst conditions. Something like the Manticore abrasive files will wear a bit faster because of the texture, which reduces contact surface and therefore increases spot pressure. But even with those, it's mostly a matter of trying to use the stone as evenly as you can and just taking off the high points when they get too out of true.
