i've been commuting for a couple months now on a bianchi pista. i really like it. it's 8 miles each way, fixed 44x16 since i have a couple hills and in case i need to get around downtown. it's a bit hilly in seattle but nothing too terrible. i have a brake but i only use it on big hills. i've learned to approach hiis (from the top) slower and just keep speed controlled by applying back-pressure and braking when neccessary. no need to be eating up tires with skidding.

i gotta say, my work day has been much better without the early morning stress of driving 10 miles (it's longer by car) and taking almost more time to get to work.
