So, far, the only horse in videos here, posted as an example of correct WP movement, that actually does have correct movement, would be the Krymsum one. He still has a two beat trot , with a tiny moment of suspension (not a walk that is in the diagonal pattern of a trot, as almost every other horse does have). His canter still has a moment of suspension, too, and doesn't require him to sling his head up and down too much, nor are his hindquarter all crooked to the inside.
Riding THAT horse would be a pleasure, but count me in the crowd that sees the extreme manipulation of a good horse's natural gait into a slow, crooked and lame looking crawl , as mystifying as to why that would be considered a pleasure. Though it may not be considered abuse, as I doubt it hurts the horse, it is just plain strange. Why would you take something so nice as a good canter and choke it down to a crab-like shuffle?
I know this doesn't please a lot of WP folks, and certainly my opinion makes no difference, but I just have to be honest to say that , I too, dont' see the "pleasure" in WP.
