marv,
What you say about the naniwa 3K is why I was surprised at the amount of stria it created compared to the cerex 5K. Am I using it incorrectly as far as slurry, water etc..?
Some say the Roszutec can be close to the 6 - 8K range.
I must have mis written about adding an 8K synthetic, the only stones I have (not necessarily using)
King 1K/6K combo
Cerex 1K and 5K
Naniwa 3K
Belgium blue
Roszutec
Black shadow
Arkansas translucent
I also have a shapton 16K but found out it does chip the edge as others say it will.
The Cerax stone you're using is the same stone as Rika 5k. Suehiro is a strange company. The stones they sell in the 5k line, such as Rika 5K, Cerax 5k, New Cerax 5k, Suehiro 5000 are all the same stone. It works at 3000 grit level. They're soft stones. Just like other soaking stones. Automatic slurry forms quickly on the surface. It can be used to jump to a Jnat, but I don't think you're at a good enough point in your progression to jump to Translucent Arkansas. There're Rozsutecs that work at 8K level, but in general they're coarser stones. They are comparable to 5-6k synthetic stones. (generally) I don't think King 6000 will solve your problem either. But I think you will get better results from Cerax. You should try...
I'm renewing my suggestion that I wrote in my previous comment. 8K Naniwa SS makes your job much easier.
