I don't have any experience with them.
But you may be incorrect about the H value -- harder pencils may have higher clay content and lower graphite content. Graphite is fairly soft. But I really don't know.

Simon,
How are "artist" graphite pencils? The sort that aren't wood-wrapped?
They look pretty crystalline. I'm assuming high-H value is higher graphite?
