I'm trying to decide how to organize my content on a site with a few levels of hierarchical content. I'm toying with the idea of creating structures for all my top level navigation items, with a few levels of nested content for sub-navs and sub-sub-navs.
My main concern is that if there are 100+ sibling entries deep inside one of my structures, how coupled are the entries to the hierarchy of the structure? Would I be able to later move that section to a completely different main navigation structure?
Or would I be better decoupling the a lot of my content into singles and smaller structures or channels, and sacrifice the relationships between the pages and the neat tree-like representation that gives clients a better overview of their site structure?
