i usually use a 12k chinese as i have it and it seems to work nicely. but i have gone from the 8k to the CrOx and had good result. one thing that i was told is that when finishing up on the 8k if you do about 10 laps with the hone almost dry, then move tot the CrOx you will have better results. it made a difference for me but i haven't any extensive testing to prove it really.

i have never used Diamond sprays but i relaly like my CrOx strop. it is a must in my rotation.
