Hey
RB1920 ,
Congratulations for the great admits.

First of all, I don't think Tuck will negotiate with Emory's offer. So, don't expect alot here.
I think I would talk to following people(current or alums) from Tuck to finalize.
1. Those working in your desired companies but have GMAT Scores as yours
2. Those coming for similar industry background
3. Those with similar work experience or other factors of your profile.
4. Current and past employment stats
If you feel that they have been successful in the past and even if it will require to put your extra efforts to achieve success, go for Tuck. Definitely, it is a big risk, it might pay you off!
Finally, Tuck is not in any major city, so I am assuming it won't be as expensive as you estimated.
Good luck and keep us posted!
