Lucinda Green is the source of the “let’s try a ring bit” on xc, in this case. I was at the clinic a few years ago at Majestic Oaks and heard her recommend it to a few riders including Elissa and Briggs.
Lucinda is a big advocate for trying all sorts of bits to find what a horse likes best, and actually brings a collection of bits with her to each clinic so riders may try them. She advised a ring bit for the same reasons Emily mentioned: increased control and rateability, reducing the horse’s locked jaws on the bit, while not being overly harsh or roof of mouth or tongue. Just like some horses go well in a myler combination bit (or other noseband-bit-combo, which may or may not be legal for silly FEI reasons), some horses respond well to the different action of a ring bit. I am perplexed at why it is illegal, because in the grand scheme of things it’s much more humane than a double twisted wire gag or long shank slow twist pelham. Could the ring get caught on something? I mean maybe, but so could full cheeks, giant ring snaffles, even martingales-- much more likely to have a horse catch his jaw playing with a martingale or even get a stud girth carabineer clipped to his shoe. Too often the FEI is a ridiculous solution in search of a problem.
For the record, I’ve watched Couture since she was going prelim and even then it made me hold my breath. This is nothing against small horses or an underdog story…but the mare just doesn’t have huge scope and as a result little room for error. No knock on Briggs, but he isn’t the same experience and skill level as KOC piloting Teddy (who also, FTR, safely banked big tables on occasion…before frangible tables existed). In this modern era of social media wildfire, officials (& rider responsibility!) should be looking out for the overall safety and image of the sport. One BAD accident, that arguably could have been prevented by “see something, say something” could do immense damage to the sport as a whole.
Which circles back to why Lauren Nicholson tactfully posted what she did.
