I know that for a number of schools, the ECNL schedule caused a variety of different kinds of conflicts this year during the Viking Cup. I don't know if this will be helpful or not, but the SCHSL does have an unofficial calendar ready for next year. If there are no changes when the official version is posted in a few weeks, it looks like the dates for Viking Cup will be March 1-4, 2012. The League tells me they anticipate no changes before they post the calendar for next year.
I hope this info might be helpful to you in dealing with your local clubs.
