I second this comment.
If you are at or below what you assess to be the average accepted student, then for ED I would aim for a school where ED might make a difference. Using ED at Brown because you don’t feel you have a chance in RD…likely means you’re wasting your opportunity to use ED. Brown (and a few others on your list) have acceptance rates under 10%.
The post from @merc81 regarding schools similar to Brown was actually sort of what I was thinking. Of the list, maybe Hamilton would be a good ED school? If the stats aren’t there for Hamilton…Skidmore might be a great alternative.
