What I pay attention to when I see people ride is not how they ride, I pay attention to how the horse reacts to the way it's being ridden. I watch shows and see all these horses with their ears back, heads up or tucked too far under, and a upset look in their eyes.. But the most tell-tale sign I see is the annoyed switching of the tail when asked to do something.
The only issue I have with showing that in reining horses is to me a lot of them look like they have gone introverted. But watch this video, watch the horse's head movements (minor ones) and how much the rider is pulling on the reins. Also watch the ears when they ask him to pick up the pace in the lope, this horse was upset.. Also I just watched some reining videos, I can easily say they were on the reins at least as much as Pat was and were using harsher bits as well
