Agree with Palomine

,people see WP & think it's easy.W/T/C around a ring what is so hard about that?? Well a good WP horse makes it look easy

but it is alot of work to train a horse to have that "self carriage"

they have to have correct training ,conditioning & natural ability to be able to do it well.Also needs a rider that knows how to get them to do it.
There are many bad examples of WP horses out there,horses that lack the natural physical ability & movement needed or poorly trained into false frames & gaits

Thinking that if they go slow enough that it correct...
