My oldest played against their 14u all-star team twice this past summer, once in pool play and once in a championship game. We lost both times. They were very gracious in victory and found them to be very nice in our limited interaction with them. I'm afraid I can't say more about them other than that, but thought I'd post something positive on their behalf. They do have a very competitive district to play in.
I would agree that there are some leagues in the LA/South Bay District that are pretty much always tough competition. However, that can probably be said of all the Districts in So Cal.
