Adding Case Western to the Tough category--the essay can be time-consuming, if for no other reason than that you get to write about something important to YOU, so tend to put a little more love and affection into it (at least I did).
Wash U, Tulane, and Baylor were definitely not mindless but they seemed to be relatively quick also, so I'll add them to the East category.
