This is where I think soccer does things better than hockey. Travel soccer doesn't have different tiers like hockey. There are also possible 10 times as many kids plays soccer so you have way more levels of play in soccer so it makes it a little hard to compare. Of course there are higher level teams/leagues that cater to the top players, but most of the leagues around PA/NJ and I assume the rest of the country don't have any exclusivity to then.
My daughter's current team formed 5 years ago where they were going into u12. This was when US Soccer changed the age classifications to go by birth year (previously they were grouped by b-days between August through July). They were the top team at this age group in their club, but weren't playing in comparable AA division. I'm guessing in hockey terms they would have been A National. Over the last 5 years they have gotten better and added more higher level players. During this time, they moved into the top division of another league, then the next year into in 3rd division of a better league and now the last 2 years have been in the 2nd division of that league. At this point it would be the equivalent of playing AAA. The only thing they had to do was apply and be accepted to those leagues. Its not like the AYHL where a club like Comcast(or whatever they are called these days) are blocking PHC from entry because they don't want another club in their area in the same league.
Hockey needs to get rid of tiers. Leagues need to allow other teams in if they think they can compete. Make it a team by team evaluation. A few years ago that Palmyra 03 squad would have been better off playing in the AY instead of the DVHL. They should have been able to move up. The Little Flyers have been fielding a lot of shitty teams for years. Those teams should be in the DVHL. Unfortunately, this will never happen because of $$$. The LF know they won't be able to charge $6000 to play in the DVHL.
