What really matters in bringing out the best/worst characteristics of a bow, is a quality REHAIR. Of course, the quality of hair is a factor, but mainly, to have a fair judgement, you need to have the bow rehaired by a luthier who is able to produce consistently superb results. One who knows to "draw" out the best hairs of the hank, regardless of the price/quality that is claimed, & to use the appropriate amount of hair for the bow. (Hair numbers & weights are really irrelevant from bow to bow, unless, of course, you're talking instrument to instrument.)
You can think of it as a sushi chef: top quality ingredients are KEY, and, since they are NATURAL ingredients (like horse hair), they will vary slightly, but those ingridients can only shine their brightest in the hands of a true master. ..otherwise, you will never get the best bang for your buck.
