David: I think Al in a wet, gritty environment wouldn't last as long as steel. But in dry SoCal, either one will work. I've got an Al 24T on my (admittedly underused) MTB that's been on there for years and looks fine. The 24T on my Atlantis is plain old steel (shows rust and is magnetic) and gets used on loaded tours. I bought a spare Al 24T on the close-out table at a bike shop a couple of recessions ago and it's still in the package.
