I'm looking for a hone after my norton 8K. I'm considering buying a Suehiro Gokumyo either a 15K or 20K. My question is with regard to jumping from 8K to 12K is that too much of a jump.

How about from 8K to 20K (Suehiro Gokumyo) also come in a 20K variety. Does anyone have any experience or thoughts on this?

My other questions is I'm thinking about using CrOx again as I miss it. I'm going to sand the back of my current leather strop with some 2K sand paper and paste with CrOx powder. Does anyone know if this will work as well as on balsa?
 
Thanks in advance for the help guys.
Cheers
