strider

Newbie here about to be fit measured for a new road bike. My current choice list for purchase are the steel models (Roadie, Zurich Maillot Jaune, Piuma and Treviso) of the above makers. I'm also open to other suggestions. If possible, I intend to test ride all. Bike will be used for long, fast, hard rides as cross training to supplement a big (5'11 230#), long torsoed rider's marathon training and possibly for duathlon events. In context of the above, anyone care to pass on their views on the relative build qualities and ride characteristics of the above frames? Thanks for your insights and help.
