Hi Dan,
Um, you should always make sure that your top choice is really your top choice when you designate that you want to do EDP. If you get in...sweet...you get to go to your top choice. If not, then on October 1, you pick new schools that you want your AMCAS to go to. So, it puts you at a little disadvantage with the other schools.
People can get a bit rude with posts, but the beginning of the app cycle is frustrating and stressful for most people, so that's why you have all the flaming in the other responses to your post.
But, it just seems strange that you would decide not to go to your first choice.
