For track bikes you should never worry about weight, you are never going to go up hill, so it is not a concern.
The Bianchi Pista is an okay entry level bike, San Diego isn't especially steep, so your BB should be high enough, and the angles are tight enough to show no major concern. If you have one, it will be plenty fine to ride it. But if you are purchasing new there are much better options, for not much more money.
The felt tk3 is only $100 more, and comes with much nicer wheels, and a much nicer crankset. Those are the two key components when looking at a complete bike. But of course you know the "best" bike that does not fit is completly useless.
