Thanks for bringing this up. I haven't tried this yet, but I've been doing similar things with a Spyderco UF. I have a translucent as well, and I may try that too based on your suggestions. So far I've used Naniwa synthetic nagura slurry, Naniwa 10k and 12k slurry, and 0.5 micron diamond spray on the UF.
Here is a WSW post desribing the UF method:
An inexpensive "superhone"
RW also recommends .3 micron Alumina abrasive slurry.
I like the fact that when the slurry is applied to the hard stone you get the benefits of cutting speed without the constant lapping needs of softer stones. It seemed to me that the slurries from the Naniwas cut faster and coarser than the parent hones. My sharpest results have been with the 0.5 diamond spray.
Keith Degras from Hand American said this in a post a couple years ago: "When it comes to maintenance stones I only use one, a surgical black Arkansas stone that I spritz with 1 micron boron carbide & water." I myself haven't tried that yet.
