I really think this rule is a step in the right direction if we think of it as a rule that is being implemented for the horse NOT the rider. The horse has little choice as to who crawls on his back, so if a few riders who know their horses are happier in a snaffle use this rule, that’s a good thing.
You can call it the “dumbing down” of American dressage, but there are a LOT of ammies riding in American dressage that will never show at an international competition but may very well have the dollars to ride at the national level. A LOT of these riders may have bought a horse that is a bit too much for them, but they insist. Sure, trainers should tell them they HAVE to show at the level that they are actually capable of performing. Unfortunately, the reality is that many trainers have to be a little more flexible than they would like when it comes to certain customers. So let’s hope this gives the trainers some outs (and the horse).
An earlier poster did make a good point that some older schoolmasters have been spoiled in a double bridle (think of those overmounted ammies I was discussing earlier). So if you could show in a snaffle and have a happy horse, why is this so awful? I would guess this rule will not be taken advantage of by very many people, so hopefully it will benefit the horses of those few that do. I see no issue with this new rule if you think of it from the horse’s point of view.
Also, it certainly requires more skill to ride correctly in a double bridle… usually = ) I think the point some posters are making is that the curb bit can be used as a crutch, and often is. I see few people riding in a double bridle that I think are proficient, but I’m also a stickler about the double bridle. I usually see people with a curb so loose (thank goodness) that it is pulled completely horizontal in the horse’s mouth and there is absolutely no difference to the rider between the two reins. They just pull equally on both… why not just ride in a snaffle? Yes, they should learn proper technique, but until they do, give the horse a break…
Another point being made is that there are a lot of upper level horses that would be much much more difficult to ride through upper level movements in just a snaffle. The curb does allow a more refined communication, and if your horse is trained well enough to work at that level in a snaffle - well done.
And for riders with small hands - I grew up riding saddle seat (full bridle mandatory pretty much always), so as a tiny tot with tiny hands, we just used narrower reins. They really fit just fine. A lot of dressage people seem to ride with very wide reins, but smaller reins do exist, and I prefer them = )
Anyway, this rule is probably not going to affect many people because they will think they’ll look “silly” if they ride in a snaffle - these are often the same people putting all of their horses into doubles at 3rd that really aren’t ready. I guess I just don’t get the whole stink about it. If it makes a few horses happier in their mouths, I’m all for it. It’s hardly the end of American dressage as we know it…
