We have been using this on our Mo. Fox Trotter for about 6 months. She is very comfortable with it and responds well. She hates any kind of bit and kept fussing and wanting ALL the reins constantly on trail rides, even though I usually ride on a totally loose rein. She is much happier with this. I wrapped the nose piece in Vet Wrap to make it more comfortable for her and have replaced the wrap twice.

I have been using this setup for about a week now and am very happy with it. Both my 9 year old TB and 3 year buckskin react well to it and take the commands. My only issue is that while it fits my TB well it was to loose on my QH so had to make some extra holes but other than that very happy.
