Dave, in response to your comment in post#69, there have been numerous attempts to MSNZ over the years about so many issues, often met with the response "I worked for "stuol" in the UK so I know, that everyone I know gave up banging their head against walls. The roll cage issue was well thrashed about and nothing at all gained.
I started my post with this copy and paste "I have no doubt you are right Dave, I still think it's pretty bizarre that you are put in a position to enforce MSNZ rules which are more strict than FIA". I thought that was showing it's not you any of us are blaming.(or shooting the messenger)
