Def. A tb/qh or Appendix. He would def. Be good for HUS. Or Hunter over Fences. You will have to work on long trot with a lowered head. I slow canter with a long stride kinda with a lowered head. In the HUS. He may even be good at Equitation.
Yea. Its always a bad idea to tie a horse with a chain over the nose. If he were to get spooked it could get ugly quick.
