Question on our Link pages

Our Link Directory currently has a PR5. On this page we have nothing more than a
list of different categories. These individual categories are pretty much all
PR3.
We are getting tons of email from people with Link pages of PR5,6 and 7 that
want to link to us but want to link to our main page not the lower PR
categories. An understandable request.
I am considering taking all of the links we have, moving them from their
individual pages (UGH) and placing them on our main page.
Can anyone comment if this will affect the PR5 on our main page?

Page in question is
http://milleniumfitness.com/bodybuilding_fitness_links/

Basically, all of the links in each category would be moved here.

Thanks as always,
