I guess im not understanding the diff or downsides to either. You are saying that you would take the cro-mo frames I listed over the leader frames listed?

Between the Leader 725 and a bianchi Pista which would you chose?

I started reading up on the leader frames and I read a few places that they tend to flex a lot, so is that what you were saying by low grade aluminum frame?

Im looking for some form of benchmark, but im thinking there is none.
