rightnow, it humble opinion, there are too many travel teams to really rank....of course there are the well known programs, ..then ther are whole buch of other organizations that field girls teams ..then some others that may have missed.
experience tells me that ge your daughter on a team that practices hard and plays in decent tournaments...a good number of programs are just an higher level of town PAL teams. but they throw a college girl on sidelines and everyone thinks that they must be legit. meanwhile, the college kid cant coach or has really no skills to be on sidleines. but boy does that program have a great looking tent at tournaments!
unfortunately it gets expensive to try out for too many teams and that hurts because you get somewhat limited as to where to play.just my 2 cents...
