I have been using this combination of stones for a while now and enjoy these stones a lot, especially for stainless knives. You could do a lot worse.
Can you please try licking the stones and report which taste better? I'm sure that it's on often overseen, but very important parameter.
I gather that chipping will be a non-issue for me so I think that I'll go for the Miyabi after all. Now I just gotta wait for them to be in stock, great
My condolences, please take care of your family and yourself.
