Thanks everybody for the feedback,
I don't like being on a site where I can't get back to the home page in one click
Nor do I, so I think usability has to win.
Might I suggest breadcrumbs?
The site is ony 2 levels deep, i.e., Index page, level 1 pages, and level 2 pages. And I always link back from level 2 to level 1.
If you have 20 navigation links, only 1/20 of the PR gets sent up to the home page immediately. Your home page should still have the most PR, but you will get a better distribution in the lower levels.
That's exactly the situation now. Every level 2 page links to all other level 2 pages under the same level 1.
Thanks for that. I will certainly consider it.
I am not so confident that I know for sure, what my target group is searching for.
Nor me! But nearly all my hits come from the deepest pages, which is why I have been trying to reinforce their PR
