Maybe a premature diagnosis but I think you have the symptoms of the onset of HAD (hone acquisition disorder) A coticule is a different animal and is cool to have in it's own right. Grit rating is debatable and individual within parameters but in general a coticule with water only is a finisher. IME it is not quite up to a 12k on average but due to the shape of the garnets that form the abrasive it will provide a sharp and a smooth edge. With your setup I would still get the 12k for now and add a coticule later to experiment with and provide a bit of variety.
