I transferred from a YHS to Michigan and it was one of the best decisions I ever made. Michigan was a much better personality fit and I found their faculty generally better (more published, too). I also had no trouble getting my first choice law firm after my 2L year. The recruiting there was identical, except perhaps for the very bottom of the class, where YLS would have an advantage. Bottom line--there are plenty of good reasons to transfer within the top ten and plenty of good jobs to go around for students at top ten law schools. I would trust your instinct on this. (Of course, it is a question you will be asked by interviewers, so do have a good answer ready.)
