Just a thought. If you are wanting to try naturals for the first time, here is a slightly different approach that might be relevant.
I wanted to try a Natural, to see what the sharpening experience was like and to see what a natural edge felt like.
Given this, I chose to get a natural finishing stone first as I figured a stone that gave the final edge would have more influence on the feel of the edge than a mid grit. I know that is only true to a point, that you can purposely not grind out all the attributes of the previous stone, and to good effect too, but....
I ended up with a Meara.
Its a fairly hard minimal mud type splash and go natural.
The synthetic finishing stones I had at the time included the Rika 5K ( leave an edge more like a 3K if you don't work the mud ), King 6K, and Arashiyama 6K.
The Meara gave an edge that in use seems to fit in range of what I already had. It has a little more refinement than the Rika, but maybe not as much as the King or Arashiyama 6K stones.
It also felt to give max performance easily. The Rika for example will give a pretty good edge, but if you want its best, you have to learn its secrets. It took me a number of sessions to get the best edge I've gotten from it. The Meara on the other hand always gives its best edge.
That said, one thing I did do was grind of a chunk of it to use as a slurry stone. This changed the character of the edge it gives, but its more of a different edge as opposed to a better edge.
Anyways, good luck on your quest
