Right-- I would working at honing your arguments, thinking about WHY certain places would be a better fit. But wait until after you know the results to discuss it-- and, in fact, wait until after revisit days. You’ll probably be able to articulate fit much better after you’ve spent whole days at various schools, including classes-- and , who knows-- you might even change your mind. But no sense arguing (and getting their backs up) until after you know where you are accepted.
