I usually finish on a C12K and hit the CrOx balsa. I'm thinking of adding a Shapton 16k and then finishing on the CrOx. Anybody have any thoughts, or suggest another stone? I'm not going up to 30k as I find the edge too harsh.
I've got both a Shapton 16k and 30k. Although I haven't had them for along time, I reckon they are both super stones. I agree that the finish from the 30k can feel too sharp on some razors. To tone it down a little I use a crox balsa strop for a few laps after the 30k and then strop on both cloth and leather. These combined take away a little of the harshness but still leave you with a super sharp edge. I actually haven't shaved with an edge from the 16k but the Shapton 12k does a great job so I can image the 16k would produce a very nice edge.
I'm guessing the 16K is the GlassStone. I prefer the Shapton Pro line even though I've read that the GS line is better suited for straight razors. The Pro 15K is very nice. It's expensive though.
