Good. The key thing here is you have a trial. So you can try different
delegation approaches and see what works and what doesn't. And aside
from the DNS mechanics, you can consider things like the impact of a
particular approach on interfaces, roles & responsibilities as well as
stuff like competition policy and the public interest. IMO it's far
more important to learn about these things than focus on which name
server(s) some zone sits on.
