I post a little while ago in the latest bought tack thread about the Acavallo Sensitive Bit and at least one of you were interested in knowing how it went, so here is a bit of a review. Firstly, the bit in Question Sensitive Bit - AC792 - Acavallo First impressions, this bit is VERY light, upon weighing it and comparing it to a more traditional bit. I got around 300 grams for a traditional metal bit and only 80 for the sensitive bit. Now the horse I originally got it for we were having trouble finding a bit she would settle in while mouthing her. We'd tried all the traditional snaffles we could get our hands on, but she was consistently unable to focus on anything other than the bit in her mouth, constantly gaping and putting her tongue over the bit. We did not go into trying this bit with the idea that we would get such a marked improvement in behaviour that we saw, we were just trying anything at that point. But we put it in her mouth and she immediately held it with just a bit of chewing. This was a horse that had flipper herself over from how tense and distracted she was by a "normal" bit. Since her trainer has been working with her in this new bit, she's said it's like working with a different horse, one that was once distracted and almost aggressive. Is now a horse that is relaxed and listening. She still tries to get her tongue over the bit sometimes, but that'll just come with time. In the meantime, I've also been using it on my other horse, and she has been just a dream to ride in it. We went to a low key ribbon day (our first show together in 8 years) and it was such a lovely experience, I couldn't be more pleased. An interesting side note, my mare is the mother of the youngster being broken in currently, so perhaps there is a component of mouth shape which makes this bit such a good match for these two. So far, I've loved pretty much everything about this bit on the horses I've tried it on. Obviously, it's not going to work for every horse. But I would say it'd be worth a try as it's at a lower price point than some of the other bits we were looking at (bomber bits and other similar mouthpieces). My only gripes with the bit are it is not dressage legal, and I can see it potentially not lasting as long as a metal bit and needing replacing in a few years, given the material is softer.
