The Medium Ring Gag is stronger than the usual Loose Ring and Eggbutt as the ropes going through the rings create leverage which will exert more pressure through the mouthpiece whilst at the same time introducing more poll pressure.
Our Snaffle is a popular bit due to the curved mouthpiece which distributes pressure more evenly over tongue and bars. With the offset center link it will reduce nutcracker action and pressure points on the tongue.
The Square Twist will create more pressure points on the mouthpiece which will make it stronger than the Round Twist and Smooth.
