I already have a coticule bout which i have to create slurry on with slurry stone so i should imagine this is classed as hard? I have just orderd a 125 by 40 coticule kosher highest quality from ardeenes Rob I no this is softer and will create a slurry quiker but what i would like to no is if any one uses one of these and how does it compare to the one i have got basicly what is the differance in the results any recomendation on how best used and when ie as finisher or not.
