I think after much deliberation I will either be going with a 1k 4k 8k Shapton Glass from Jende, or 1k _k 8k from somewhere else. Already have a Swaty, a Thuringen (very fine) and a J-nat (very fine)

I have not decided between them and am NOT looking for advice as to this.

What I want to know is which is better for the Naniwa middlestone, a 3k or a 5k?

Also, if I have to buy the stones piece meal, would it be better to get the 8k or middle grit stone first?

I was thinking the middle grit, then just be real patient on the Swaty, then finish up til I can afford the 8k.
