Fager Harald is the ideal choice If you would describe your horse as the following;
Harald is a stable, sweet-tasting bit.
A steady model for horses who needs to seek more contact and maintain that contact. Harald is especially suited to horses who have a sensitive tongue, mouth corners, and cut easily, developing sores.
Harald is designed to be more stable in the mouth and less confusing. It works to keep the correct balance point (BP) in the mouth. If you have a bigger bend forward, you will also move the BP forward and reduce the effectiveness of your aids.
Harald is the perfect bit to use in combination with your other bits.
