Hone selection limitation.

Hi,
Serious head scratching zone now people. Get in recomendation stance.

Razor Strops, Hones, and Accessories
I'm on the verge of buying my first hone set and from what I've read, the outstanding first hone choice seems to be the Norton 4k/8k which I'm happy with. I want to get a 12k as well and I've been told by Lynn that the Naniwa 12k is delicious.

Now the classicshaving.com site doesn't list having the Naniwa 12k superstone which makes me reluctant to buy one, simply because of saving on the combined postage of the two stones from the one place, as I'm shipping to Hanoi, Vietnam.

There *is* a 12k waterstone listed on that page here

Now, I understand it's a natural stone, therefore not exactly 12k.

And a question emerges:
How does this 12k waterstone stand up to a Naniwa or even more helpful a question, is this what I'm looking for to touch up razors that are aren't shaving as well as they could be and are beyond stropping?

Edit: Or maybe a coticule?

Thanks for your help!
Looking forward to stopping reading for an afternoon, and starting honing.
