Honing the Cylinder--How smooth is smooth enough?

[bama]

The acid no longer highlights any aluminum on the cylinder. Now, I am in the process of hand honing the cylinder and I have one spot that I can still feel with my finger. There are no gouges and I can't snag my finger on anything, but I feel a rougher surface at the top of the cylinder. I know I should be using a ball hone, but it wasn't too badly scored, so I figured I would save the $$ and spend a 1/2 hour doing it by hand. How smooth is smooth enough to run?

Knock the glaze off

then quit.

Don't hone so much that you have to have an over sized piston or over gap your rings.

I haven't honed out of the nikasil, but it just isn't quite as smooth as the rest of the cylinder. I don't want to be overly picky, but I would rather not learn a lesson by wrecking a piston. I tend to be a little over cautious when rebuilding and repairing stuff, so I just need to know what is acceptable.
