I'll be the first one to call myself an amateur, but even I wouldn't have picked that line. Having 800 people all yelling directions at the driver is terrible, especially when the spotter is the QUIETEST guy there, and he's just making silent hand gestures and providing no real information.
And most importantly, keep the booze off the trail. You make it through a day of obstacles like that without rolling your Jeep, then you celebrate with a couple beers afterward. People put too much time, effort, and money into their Jeeps to waste them like this.
