He says the same about shapton glass stones past 8000.
Not sure what Sham's point is as presented, but I think that one of the nice things about both the Naniwa SS 12K and the Shapton Glass 16K is that they are very precise. I normally don't use more than 10 strokes on either with minimal pressure and am very pleased with the results consistently. I normally with use 10 strokes as my standard for finishing with both a Coticule and an Escher as well and in my opinion, all four of the stones mentioned will burr an edge if too many strokes are used.

Have fun.
