My issue with side reins is that there’s no way to adjust them on the fly (i.e. in the middle of an exercise) based off of the way the horse is performing. Also, when adjusted loosely, side reins encourage nothing that couldn’t be encouraged without them. Adjusted tightly, they interfere with the horse’s natural way of going. I can see the value of side reins on a schooled horse who understands contact, but an unschooled horse is liable to learn to bend away from the circle to evade the pressure of the side reins.
The young horse, if given free use of his head and neck, and if brought along slowly and methodically, will learn more or less on his own how to balance on a circle. Teaching him the basics of contact can be done more effectively through long lining or groundwork.[/QUOTE]
I haven’t seen sidereins used to any good effect on a young, developing horse.
The peculiarity of my situation, though, is that the best riders/trainers I have access to have sworn off all “gadgets,” and the people I see using sidereins are doing a lot of other things wrong, too, and have poor long-term results. So I am keeping an open mind that it’s possible for a good trainer to use them well on a young horse. I’ve seen videos of schooled horses going well in sidereins, videos showing how to adjust and use sidereins. But that’s different from seeing how they work in schooling a green horse.
I longed for a while in a bridle, line across the poll from the outside bit ring. Then a rope halter. Now I have a European longing cavesson that can be put on and taken off under the bridle, and the noseband is light enough that you could leave it on to ride if necessary. I like that the pull/weight of the line is on the front of the nose, meaning that the head can be nudged to an inside bend; the rope halter tended to encourage a counter bend by pulling on the chin.
I have found that with some careful attention to shoulder-in/shoulder fore on the longe line, I can get maresy to stretch down and carry herself with just the cavesson.
