Love all the butthurt platinum parents chiming in. If your bender plays for an org where the top 6 on the platinum team are better than the bottoms 6 on the elite team you’re in the wrong org and should leave. Of course there are kids playing platinum that could play at the elite level but it’s not half the team sorry platinum parents. And of course there are a few platinum kids floating around that will wind up being better hockey players in high school than elite kids. But there is still a big difference between elite and platinum. If there isn’t why are all these platinum parents looking to leave the platinum level to get their kid to the elite level? To your question you are probably better off moving your kid down at the elite level than moving him to platinum.
For most teams, the difference is the top 5 kids. A competitive elite team typically has a top line/pairing that make the team. Top line of a competitive platinum team is generally interchangeable with the middle and bottom of an elite team.
If even "most" of the players were actually elite, New England would be sending hundreds of kids to D-I & D-III at every birth year.
Everyone's situation is different, it is difficult for others to tell you what is best for your kid and family. My kid moved from a bottom black/platinum to a bottom elite and then to a top elite team. The difference in talent level and work ethic of the players is noticeable every time he moved up. The same can be said about coaching. In the end, very few kids in the EHF elite division are able to continue on to play on top U14/midget teams. My suggestion is to figure out what your kid needs at his current stage of development and do not worry too much about labels.
