What partition type for large partitions?

[b r u ma]

hi,
This is perhaps not appropriate question for fedora-test-list at redhat.com
list, but I don't where else to ask...
I'm installing Fedora Core 1 to my new hard drive (120G) :), and I want
to have one larger partition approx 85G as logical drive.

What type (ext2, ext3, reiser) would be best solution, so that I don't
waste to much space on slack?
