My Ritchey Road Logic frameset came with this steel fork installed. I have since replaced it with CF (lost the steel one to a car who rear-ended me with the bike in the trunk).

I could feel no ride difference at all. Both were pretty flexy. Watching the front hub as I ride over chipseal, the hub seems to move move back and forth 1/2" to 1" as the fork soaks up vibrations.
