With the really easy install of RH7.2 I wouldn't see a reinstall to upgrade as a problem. When this machine (or elements of it) becomes my second box I'd like to try Debian - sounds like even more fun.
Indeed, if the install is really that easy (and I'm sceptical given the failed 7.2 upgrade reinstall I did before leaving UEA), it's not a huge impediment, but I'd still rather avoid unnecessary work.
