This really does sound like a great ride shaping up.
I've made my decisions related to handle bars based more on width, reach and drop vs material. Generally (the exception being my touring bike) I like 42s with short reach and shallow drop. Have you used the Bittoria Diamante Pros before? What kind of mileage and puncture resistance do they provide?
