Bart when you explain . Speed with water moderate or slow. Which type would you prefer slow or moderate? I take it moderate would refine more with water and slow would'nt do much. Or does it just take more laps with the slow coticule as apose tom the moderate coti take less laps. They both do the same job but one is just a little slower? Or does it mean the moderate coticule will do a better job with water? the slower one has'nt got enough cutting power to pick up keeness? If you could explain if you understand what i'm asking.
