I, like Stan, don't have a horse either but "of course" do have a opinion.
My one problem with our Rule Book IS AND HAS BEEN FOR THE LAST FIFTEEN YEARS that although it is over all a well written and consice guide to building a race vehicle, it remains lacking in technical scetch's such as the helmet restraint rule, the window replacement and attachment rule, etc.
While I understand the complexity of any one rule or explaination covering all classes, I would ask (again) that no rules be implemented with ambiguous or (often) any scetch's or reference points that can be easily understood.
I would also (once again) like to never again see any rule enacted requiring change in products or useage without advising the entrant a well defined product or source of what meets the proposed new rule (think windows).
A few simple scetch's can be worth a thousand word's and maybe save the tech folk's a lot of needless evening phone calls from us Dummies.
