I think I will also go with Chosera 600.
It's pretty hard and fast stone as I can see.

I try not to mix hones.
That is main reason I am looking for Naniwa (I already have 1k-3k-5k-8k-10k). I know there are better solutions but as I told my brain function way like it function.

I need recomendation from user who use these stones.
I have Naniwa 1k (that is my rougher stone) and sometimes it is not enough for remove bigger chips in reasonable time so I decide to buy one...
