Would you describe your horse as the following;

• Pulls the reins out of the hand, overreacts when taking the reins.
• Unsteady in contact.
• Too stiff on a regular straight bit.
• Does not seek contact.

Nils is a stable Sweet Iron barrel bit. The middle part of the bit has a naturally quick lock in all directions, but rotates to provide a more flexible feel than regular straight bits. A stable model for horses that need to seek more contact without becoming too stiff in the hand. The bit has a shape that follows the horse's natural shape over the tongue. This design is ideal for horses that easily get sores.

Nils is a perfect bit to vary with.
