Generally I go 120, 220, 320, 400, followed by stropping with green compound. I find it to be a somewhat toothy edge that cuts better and lasts longer than a multi thousand grit edge.
With some of the more modern super steels I will add 600 and 1000 grits to the process.
With the exception of straight razors, I hardly ever use my Shapton stones that go up to 10K grit, just not worth the time.
