What hook for installing a large list of field options?

Question

If a custom module installs a dropdown-style field, using a large internal list of options (about 200 items), should this list be populated in hook_install or hook_init for greatest efficiency? Yes, I know, with such an extensive list, I should provide an ajax-driven widget for ease of use, but at this stage of development and my skills this is a side issue :)

Answer 1

I would probably use the List field predefined options module.
