From Brittany Pozzi on this Hackamore:
This is my favorite bit in my collection. I have ridden two different horses to world titles using this hackamore. "The hackamore is great for a horse that just needs some guiding around the turn or one that does not like a bit in its mouth. The side pull action on the shank makes it easy for your horse to work without getting in its way and gives you a small amount of lift. The rubber covered metal nose piece gives it great balance on the horses nose and more control for those long runs to the barrel.
