"Headroom" in datafiles?

I'm curious how much "headroom" people like to maintain in their datafiles? We have a large data reorganization procedure underway as part of our DR discovery process and I was playing around with some ideas.

I was thinking, we could allocate a fixed size for each datafile (say 32G for example) and not worry about space or autoextend until we reached some threshold. OR
I could fix each datafile to have 10% free space at all times OR
something similar.

I think what bothers me is knowing that some of my datafiles are "99%" full for example while others are 5% full in the same database.

Do any of you get bothered by datafiles being a certain % "full"?

We've got gobs of disk space "right now" so I've been pushing this to the back burner for a while for coming up with a cohesive policy on datafiles.
