Thread: Method to test stone's finish?

Is there some method to test stones against one another to determine which will finish smoother?

The obvious answer is to hone and shave with them both but is there a more direct less subjective method to limit the variables which doesn't involve electron microscopy? My honing skills haven't developed well enough to be eliminated as a variable.

I would like to determine if my HSB & CO OVB is adequate as a finisher. I have a Norton 8k and sometimes I will finish with a few strops on a crox paddle.
