This is the tricky thing about your portfolio- if we take something out it will be extremely hard to find a similar school to replace it with.
As we both well know, most of the elite cluster have yet to return to their previous love of young candidates. Even if you are enrolled in such a program, it is important to consider whether employers (and the career services offices) are prepared to handle students with limited work experience when your average peer has 5+ years.
Since you found Duke such a strong match, I am reluctant to remove it from the list.
Re: Babson, I do not recall it being particularly open to young applicants and the class profile appears to reflect this. However, Babson is essentially the "mother ship" for entrepreneurs so I understand why it appeals to you.
While I think we discussed it before, Arizona (Eller) is another possibility. It is strong in eship and has an mean nominal work experience of 3.3 years!
UNC offers a very nice blend of strengths (GM, eship, location in NC). There is just that pesky 2 year minimum work exp. requirement. However, the exchange below suggests you might be able circumvent the work requirement.
"Q:If I have less than two years of full-time work experience, will my application be considered?
A: We review every application we receive, regardless of the amount of work experience. But applicants with less than two years of experience are not likely to be competitive in comparison to other candidates at UNC Kenan-Flagler.
Q: I worked full-time before I received my college degree. Will you consider that work experience?
A: Your full-time work before you earned a bachelor's degree can be considered. The quality of work experience is as significant as the quantity. The Admissions Committee will evaluate the degree and progression of your responsibility, supervisory roles and the managerial promise of that work."
