I have to agree with Simon here.
In addition, if there was a limited budget due to some unforseen reason or whatever (eg a third of the field dropping out a la Norway) I'd rather that money left was spent on making the event as good as possible rather than have a mediocre event for an awesome prize.
People would be reluctant to recognise a world champ who had won on a "club level" course but got an awesome prize, surely.

Too many tinker projects, not enough working rifles.
