Bow hair thickness

[Justin Leonard]

Thanks Ken that pretty close to what i was asking. I'm not sure how to clarify what i mean by amount of hair. I guess its more in regards to say ounces of hair; or like a whole hank of hair or most of the hank. Im just being curious about others experiences with what sound difference they notice but you've pretty much answered the question. Sorry to anybody whom my restrictions may have limited as it will always be a combination of things for our instrument (any instrument really) and how the player uses them.
Off to practice for summer pops concert. Cirque de Symphonie
