Does a dressage rider use a forward seat? Is someone using a forward seat doing a W/T/C incorrectly? If the horse doesn't have a bit, will he be allowed to take the dressage basics test? What if the rider is neck reining his horse? Is that correct?
How would this guy do:
Or this one?
Would they fail basic riding? Or are they good riders riding in a different but equally acceptable style?
Does a polo player modify the dressage seat, or the dressage rider modify the polo seat?
