Boston College (Carroll) vs. Johns Hopkins vs. WashU STL Undergrad for IB placement?

I am currently a high school senior and am trying to decide where I want to spend my four undergrad years. I am pretty sure I want to do investment banking after I graduate and am looking for the school that is going to give me the best placement.

I am deciding between Boston College (Carroll), Johns Hopkins, and WashU STL (Olin). I know BC sends more kids into IB every year than the other two, but am not sure if that might just be because more kids want to go into it from BC than the other two.

They are all around the same price for tuition so that really isn't much of a factor.

I would also be able to play varsity baseball at Hopkins and WashU, but not BC and have heard that playing a sport makes a pretty big difference in IB recruiting.

Any advice or suggestions about how these schools compare in relation to their IB placement would be much appreciated.
