I guess you've already made your decision, but I just wanted to add that when you write a school a LOCI that says you will attend if admitted, it is pretty damn close to being binding. I've heard stories about people doing that, then not going to the school they wrote to and their other schools rescinding their offers on account of the ethical transgression. But then again, these are just stories I've heard and I don't know if they are completely accurate.
That said, I'm attending Fordham next fall too. See you there.
