Putting aside the professional level, I’d rather see more use of the reverse diagonal. I use it where there is a problem for an AR on the path. (Awful mud, trees, jump pits, etc.) I’ll also do it certain sum scenarios. One field I used to ref on regularly was horrific for a standard diagonal on early morning games. By flipping the diagonal, no one on the ref team was staring into the sun. Most folks understood and liked it; others looked at me like I had two heads. (Long ago, when reverses seemed more common, someone told me that when shadows are long, the ref should run the same diagonal as the shadows—it really does make sense.)
