I was the same way great sitting down but ok standing up. But i started fooling around with my strap untill it felt just right which is just at the waist if not just a little bit higher and i have the neck almost always angled up toward me just a bit I have found it's easier for streches and speed.....at least for me. Hope something I said can help you out. If anything just play standing up for a full day of practice by the end of the day it should be second nature to you.
