From what I can tell, the only ones wanting the nitrous are the folks running the org. As far as I know Rodney, none of the pullers interested in the class want nitrous and they are trying to convince the organizers to keep it out. Or so I'm told.
I have talked with some of the guys that are wanting to start this 2wd class. I dont like the No2 idea either. Keep it the same as any other 3.0 class. If they want to spray let em stay in the open class.... $.02
