I have a Takashima finishing stone from JKI, which I currently use after my Bester 1200 in regular sharpening (not wide-bevels). I'm considering replacing the Bester 1200 with your JNS 800. Do you think that would work, or would it be too big of a jump?
For kasumi finish I also have the Gesshin synthetic Aoto, which I would use in between the two, on wide-bevels only. Does that make sense?
