1. Get his teeth floated.
2. Ditch the tie-down unless you don't feel safe without it.
3. Switch the mechanical out for a leather-nosed Little S hackamore.
4. If you still feel the need to change to a bit, try a loose ring snaffle with a smooth broken or French link mouth first. If you want to use a curb, go with a smooth dogbone with short to medium length shanks.
Could not agree more! My daughter and I run barrels in a Little S hack.
If the horse works good and prefers a hack, the Little S would be good.
