Coti's are great! If I could only own one stone it would be a coti because they are so versitile. The heavier the slurry the more cutting power, and in clear water it's a great finisher too. Here is what works for me: Take the razor thru 1k-8k progression. As soon as the razor starts grabbing arm hair move to the coti on a very light slurry. The slurry should be just a bit cloudy. Make about 25X pattern stroke and clean the coti and repeat this step. Then, move to clear water with little to no pressure 25X patern strokes and clean the coti repeat this step. Test the razor. I can get the razor to pass a HHT using this progeression.
