Profile Evaluation for Harvard 2+2 program please!

Letters of Rec's:
Letter's of rec should be pretty good, they will be from:
- a mentor of mine that now works for Cornell
-either the Vice President of Virginia Tech who doesn't know me very well or a chemical engineering professor who knows me very well. Any suggestions on which I should ask?

If you are still reading you get my up most respect, thanks.
