I'm a Campy girl myself, but everything I've heard about current 105 has been really positive. It used to be a bit more of a downgrade, but what I've read suggests that it's really improved from a performance standpoint. So, if you can handle the weight penalty, I'd strongly consider it, especially if you don't intend to use this bike for racing.

I'm sorry; I can't help you with those specific wheels. I don't know why they wouldn't be appropriate wheels for this bike though.
