Hi pikato! I'm also a small rider... a whopping 5 feet tall even though I live in md I bought my bike down in texas as my bf lives there. i have a bianchi eros donna (it's wsd) and love it. i also tried a specialized dolce but didn't like it. the bianchi has great campy parts, shifts really well. i've never tried an orc3 so i can't compare. but if you are willing to go to the houston area, the bike shop i went to is called bikeland and it's just north of houston in spring tx. http://www.bikelandusa.com
hope that helps some! good luck and welcome!
