As to how they handle...there are many variables but I have a Gios A70 which is aluminum and a Compact Pro which is steel. (I never built up the Gios-Torino). The steel frame is without a gruppo, presently. It is on my Torelli steel. They have had the same gruppo (Campagnolo C-Record), forks, saddles, stem and bars and wheels (Mavic CXP33 rims/ DT spokes). The A70 is a little stiffer and really responds to sprints or hill climb efforts. It handles great! They both have tight wheelbases. The Gios steel is more plush but is still 'precise' in its handling. There is probably more to do with geometry than material, though, but I can't quote exact figures. I'm too busy smiling and whistling while I ride these lovely things! It is still a good sprinter's frame for steel. I prefer steel for longer rides. I never did 'cotton' to carbon. Too 'buzzy' for me.
