Hi everyone, I'll be filming professional skateboarders riding this huge drainage pipe tomorrow. The director is asking me to fly straight through the pipe, then up and out into the ravine to show off some of the scenery. I'll have my prop guards on and do test runs without anybody there beforehand. Would it be wise to fly in Atti mode? It's just such a unique shot, any helpful advise is greatly appreciated. Here's a picture of the pipe.
