Steve-
Will there be a minimum sail area as well? Also will there be specific sailmakers or will that decision be up to the individual sailors to make?
What specific modifications are you speaking about? The stock ARC/SC22 sail plan [main&jib=360sqft]with large spin [742sqft] falls into the 1100-1200sqft range.
I assume that these tuning events will be across the country or in the central section [say Texas to Chicago ]and not just in one area??? Some people won't participate if they have to drive 3000 miles one way to race.
