I know I'll take some flack for this, but here goes.
I'd advocate moving Stock, Super Stock, Comp, etc. out of the National Events.
Instead, have every division hold a Sportsman National event. The Sportsman racers would be the show, not the filler. There could be a World Champion crowned based on points earned at these Sportsman National event, class eliminations could be run at every one of these Sportsman National events, no ridiculous quotas, etc, etc.
Way more on the 'Plus' side of the paper than the 'Negative'.
Race safe!
