If a committed user wanted to play around with aerodynamics, it would make sense to add vertical "winglets" to the screen to create a channel which would direct a more-coherent stream of air over the rider's head. Just a thought...
I think that is quite right and we have experimented with such a system. It does improve the airflow, but we concluded that the "winglets" would probably have a short life in the bush ! I guess it's all a compromise.
