I have had quite a few and a variety of pithy staves. I don't worry about it much anymore. It seems to work itself out or in one way or another. Being mindful of it, but not worrying about it, is my approach now. The first few weird pith staves I had, I noticed I worried way too much before even starting the bow, which led me to the way I go around it now. Pith can be finicky, I've seen it run all around, but again I've never had it bother my end result too much. If this info doesn't help, I understand. Take care.
