I mostly use my road bike and my beater bike (an old touring bike I got at a yard sale). I have a mountain bike (used to ride off road--one concusion later + five stitches + one VERY upset little 5 year old girl put an end to off road for a while!).

If you are going to be commuting with the bike, why not look at a touring bike? gives you the benefits of road bike with a more upright position of a hybrid. bianchi makes a great touring, the model is called the "volpe."

keep us posted!
