Happy Mouth Loose Ring
My horse was so afriad of the bit and really hard to start under saddle as a result. This bit has been such a blessing. He accepted the contact very nicely over time. Our bit has a single joint and is basically a plastic loose ring snaffle. We showed just fine in it all season at training level dressage. It was USAE legal. It is also fairly inexpensive which is nice for the growing horse and if it is an intermediate bit for you.
