Ultimately, the "exclusion model" is doomed to fail. According to Greg's Tip#1 for writing a rule, no small group of persons can ever think of all possibilities. And, as we all know and as Andy is demonstrating (I know he's just trying to get a rise out of us) racers will be racers and will look for loopholes to jump through, despite being obviously contrary to philosophy and intent.

These characteristics are simply incompatible, and may ultimately lead to an "inclusion model" for chassis (though that's not being seriously discussed yet). However, certainly speaking for myself only, I can say with confidence that I have zero reservations about supporting ex-post-facto exclusions of chassis that I don't see as meeting the class' philosophy. So - and the whole point of my posting above, for everyone else's sake - I'd suggest not getting too clever without asking first...just food for thought. - GA
