So there's 2 schools of thought here, right? On one side of the line you've got the folks who want to set the height of the bass by bringing the nut in line with the eye or eyebrow, and on the other side you've got the folks who want to set the height of the bass by bringing the bridge in line with the knuckles. I'm a knuckles guy myself, since I appreciate having my German bow getting nice and close to the bridge for power and clarity. I like mimicking Gary Karr's Koussevitzky lines the way he does them and imagining that I'm taming an entire orchestra. But then I understand a person not wanting to have the bass too high for lower position playing comfort, and I've seen enough people bow to know that if there's string winding exposure anywhere chances are good it's been touched with bowhair too at some point in time. So which side of the line do you stand on, and why? I don't care what endpin arrangement you're using, but I don't mind knowing either. I use a straight endpin and play around with a plain old rod I bent when I get bored holding the bass with my knee.
