I have an organization tree with a single top level. The top level can have any number of children, the children can have any number of children, etc.

The question is: which List implementation is better here? If I know the organization tree will stay relatively small and won't change too often, the ArrayList is a better choice. If I know the tree might be quite large or might change fairly often, would LinkedList be a better choice?

I'm using Hibernate (mostly Criteria) queries to retrieve the data. The methods of the Criteria object return List. I'm not going to rip out all of my database access code for one Use Case.
