Sorry, I have no idea how the elite teams have done.
As for Junior Gold. In Minot I don't think the team ever had the talent that varsity High School has had but I think in their heyday they would have beat the JV team pretty handily. Junior Gold played a pile of games. They, of course, had league games but they also played in turnaments. I know they went to South Dakota for a turnament. I think they also played Canadian teams. Pure and simple, if you wanted to play a ton of hockey, you went with Junior Gold (unless you were way skilled or something like that, then you probably played HS).
