Finally, I think the 1A division plays out best as a 3-5 game series between:  

1. Brebeuf
2.  HSE-B 

Team Notes:

Now you can switch the  South Stars White and Lake Central White from 2A to 1A and have any combination of the four teams.  However, I think Brebeuf and HSE-B would make the best of a 5 game (or 3 game) match-up.  The key would be hopefully that one of the teams doesn’t win 2 games in a row and spoil the championship weekend - and I believe that’s what would happen if Lake Central White and South Stars White were to be thrown into 1A.
