As having seen a good portion of these in person I would have to say the Rossin or the later Merckx pro. Oh wait did I pick the two bikes that I haven't seen in person that I know are at your current locale? Yes, I believe I did! I won't give my "I have all these fine Italian SR equipped bikes I don't know what to do". Oh, wait I did that too. Good to here that you found your holy grail, the De Rosa Primato.
