Why no iro?
Also don't buy a bike planning to replace stuff. Most of the parts on either of those bikes will be fine for quite a while.
pedals, saddle and maybe tires are all you should be worrying about.
The difference in ride is due lagely to the angle of the head tube, if my memory serves me correctly.
Also I think that I could beat someone on the track riding either a Pista or my beefed up Steamroller. If you're really going to ride track and that's it, don't buy either of these bikes.
