When you have a razor that was properly honed on a 4k/8k Norton, what is the best way to finsh it on a yellow Belgian Coticule? It is said that with water only, the Coticule is about 10K to 12K grit. How many laps would be recommended? What are your experiences with a Coticule as a final polisher?

I don't have anything against pasted strops but I would love to be able to work with a Coticule only and get a keen and shave ready edge. Any feedback is highly appreciated. Thanks!
