This bit will retrain a good light head set if you keep the
curb chain tight. This bit is safe to use in all riding situations including
trail riding. It is comfortable for the horse to use and won’t rub or
become uncomfortable used long term. It also won’t cause vices. If the
horse ducks his head to evade the collection, take the draw reins off and use it
without them for a week or switch to another bit for alternate stimulus.
It is not nice to use this bit with a loose curb chain
because it will pinch the corner of the mouth between the curb chain and the
mouthpiece like many other curb bits. It is designed to lessen the pressure on
the bars and mouth already so be sure to adjust it properly.
