I have a VeloVault and this is a reason I am hesitant about getting a disc wheel because I fly to almost all of my races. The hard cases that don't have a pole seem to use thicker plastic. Would be neat if there was a secondary off-center location for the pole. That would help still be better than not having one at all.
Probably worth getting a separate case for the disc wheel, tbh
It should be fine. My partner and I have done ~100 flights with our BBAs. She normally has a disc, I normally don't. It's never had any damage. I don't think I've even used the stick with mine since ~2014.
