My collection is SLD and ginsan knives, and future purchases will continue to be semi-ss, pm or ginsan. My current stones are Shapton pro 2k and Rika 5k, so I figure a 600-800 grit would be the next best purchase. Is there any consensus on which stone in that range is best for the steels I gravitate towards? From my initial research it seems chosera, bester, cerax are each ok options? I'm thinking bester or cerax before chosera as I don't see myself using a low grit very often. Shapton's only grit close to my range are either 500 or 1k so I dont know about that.
