Thanks and hone on!

I have 2 different white translucents, a "true hard", and a surgical black that I regularly use in the final stages of a razor session. I have finished razors of various grinds on all four. In my personal opinion, the surgical black is the best finisher, with a higher polish than either of the white translucents or the true hard. The true hard would be next, followed by the white translucents.
With that all said, I have absolutely no means of measuring the density of the novaculite particles in the stone, so I have no way of truly discerning which is providing a more dense, and thus finer, cutting surface.
They could all be "identical" in terms of density, or at least as close to identical as any natural stone can be said to be. It could simply be the individual stones that I have. It could be all in my head.
My standard oil progression is as follows: 1k Lansky diamond benchstone, soft Arkansas, white translucent, surgical black. I have a couple different soft Arks I use, a couple different white translucents, and I will sometimes use the "true hard" in place of the white translucent as a pre-polisher.
There are a couple factors besides density that will effect the performance of Arks as well. The means of prepping the surface of the stone, and the techniques you use. I also find that some steel responds to the natural Arkys better than synthetics, while others have the opposite appearance. Again...no real way of measuring this to a standard, but it is my impressions.
All of my oil stones are dressed the same way: lapped with a coarse Silicone carbide lapping stone, prepped with a Lansky 800grit diamond benchstone.
I use my oilstones for knives as well as razors, and the stones that see a lot of action with heavier knife steel seem to be more burnished than those that get used rarely(I have a standard hard that almost never sees daylight, and I use 1 of the white translucents much more frequently than the other because of size). I don't know how others "burnish" their stones, but I will pull out my surgical black and just run a heavy knife blade on it for a couple hundred laps while watching tv. No pressure on the blade, just rubbing the steel gently on the surface of the stone, allowing them to polish each other. Does it make a difference? I don't know, but I hone with oil stones by hand(no stone holder, just in my hand), and the action is very soothing to me, so it's as much a practiced form of meditation as an actual effort to polish and burnish the sirface of the stone, and the edge of the blade.
I know that is way more than you asked for, but that is how I use my Arkansas stones. To be 100% honest, I get edges from the surgical black that are every bit as keen and comfortable as my Shoubudani type 100 with Asano nagura progression. It takes longer with the Arks, and you have to pay closer attention to know where the blade is, versus which stone you should be using, but with careful observation and good stroke technique, it is my opinion that a comparatively inexpensive surgical black can be a top razor finisher, comparable to the highest end Jnats.
As with most things honing...please bear in mind that this is strictly my experience. Your mileage not only may vary, but should vary...
