The key to all these relatively local programs is can they build behind good early success. Will take a while but folks have to be patient as most of these programs do, as others have said, have great coaching / contacts etc..
Eclipse has loaded 17 and 18 teams as New Canaan / Darien great at those ages.
Express North followed the success of the 18s with the 19s now.
Primetime, while not new, does have loaded 18s and up. Can the repeat the success at younger ages?
