pctfree for Indexes

In regard to Oracle V6 and V7 databases:

I am attempting to reduce overhead in the database. For tables that are never updated, we set pctfree to zero.

My question is this: For indexes, should the same approach be taken? Does "Balancing the Trees" constitute an update to either the branch or leaf nodes? Should my pctfree for the index take into account the possible difference in the (stored) length of my keys?

Opinions?
