I have a 320 grit flex-ball hone. I've done 3 engines with it now, and no issues at all with ring seal. they don't burn oil or smoke at all. all 3 engines were "refreshes" where they were taken apart to a bare block, the bores had very minimal wear, so the whole block was cleaned up, I honed the cylinders with the "dingleball" hone, had the machine shop balance the rotating assembly (new rods/pistons) and I assembled the motor.

if a block is bored over at all by a shop, then yes, I would have them also do the hone job afterwards (isn't that included with the over-bore job?) but if you have a block with bores in great shape showing minimal to no wear, then why CAN'T you use the flexball hone? you're not trying to re-shape the bore, you're just trying to scuff up the walls and give it some "tooth" for the new rings to seat against.
