You can see and read about the HR (and HC) glass stones at Dictum and Aftramestokyo.

Yes, the HC series polishes much better than the HR series. The 8k HC is about the only 8k that makes a decent shaving edge for me.

Shapton recommends the 8k HC over the 16k HR for razors. I think that I’ve posted that email here somewhere.
