I'll also caution you that any list you come up with may not be valid next year - rules always change. Last year was the first time those plastic air tanks are a prime example - last year was the first time they were legal. I know (from personal experience as an inspector) that they were a huge pain during inspections. Speaking personally (I have NO insight into the GDC or what they're thinking on the rule book), I wouldn't be surprised if that specific rule changes again this year to help make things run a little easier... It's just a nightmare for both inspectors and teams to trace those plastic air tanks back to specifications and show that they are rated for the appropriate air pressure.
