Kitiyama 12k

Any one use 12k kitiyama stone i have purchased one as a finishing stone. Is it best to use with or with out a slurry for final polish i have tryed after using my norton 4k/8k pyramid and kitiyama does'nt seem to make alot of differance. My .5 cronium makes a massive differance i'd like to see the benifit of my kitiyama. Not many people seem to use this stone i was recomended the stone by a honmiester and lynn also has it on his dvd even though he demonstrates with a coticule. Thanxs gary
