Double Major through FSB Econ and

I know that I want the Economics degree through Fisher but I am curious about whether or not I should pick up a second major if I choose the FSB bizecon over the A&S B.S. in Econ. I was thinking about either Finance Investment Track or MIS.

I have heard that most people that take the FSB bizecon do so as a secondary major, does anyone know what they would take as a primary?

I am mostly interested in getting into an MBA program (and/or a CFA if I choose the Finance Investment Track).
