A good LBS will encourage you to take some spins around the block on several models. As stated previously different brands have different geometries... I am also short (5'1''), short torso but like to feel stretched out when riding. I LOVED the Coppi - it was a beautifully crafted, sexy bike and only about $1200 - but it just wasn't comfortable for me. I wound up with an Antares Litespeed - comfy - much more $$ - but the COPPI was still prettier! The moral again... test ride, test ride, test ride.
