Merit aid can be a useful screening criteria - at least to rule out colleges that don't offer YOU assistance.
Are you an East coast or West coast person? If West coast, then you are down to 3 schools. Are you an engineering extremist? If so; then I suggest UC Berkeley, Caltech, MIT, Stanford & possibly Columbia.
Of course, in your case, I might forego college all together and teach the world what the best can do so all can learn from your infinite wisdom.
