I just wanted to add that I lived the video.
That horse does the same thing over and over and over. He should know his job by now.
Just remember this horse, just like Stacy Westalls:
A) was trained to the 9s with a bit, and one with leverage to boot.
B) eventually you have to put the bridle and shank bit back in its mouth to get that collection and responsivness again. I'd be willing to bet they ride 99% of the time with a bit in (likely with leverage) and 1% of the time bridless.
