I have no idea, which is why I opened the thread and asked that question.
What I've since learned is that there are privacy issues that you have with a corporation and LLC that you don't have with a trust. With a corporation you also have personal property taxes that have to be paid, etc etc.
I've a mind to set up the NFA trust regardless of having the LLC and the C-corp, unless someone can chime in and tell me why passing on the trust is a better idea.
