I really like the ceramic stones. When I hit them in my progression I notice a huge change in edge refinement and overall reaction in scratches. I do not think I would like my wicked edge nearly as much without them and I’d recommend them as a big upgrade (not in cost, but performance). Currently I then start stropping from 5 or 10 micron on after the 1600 ceramics. It may be repeating the grits, but I feel the results are very different as the ceramics add a haze/cloudiness (while removing the diamond scratches) that the strops then take out.
You are right on the edge angle being locked down on the wicked edge. I think it gives us a unique ability to stay on the stones further into the process, which I like. I think the stones by their nature have a higher level of exactness. I am hoping that the upcoming Shapton stones just build on this and let me start stropping even later.
