I also have the d. Cook version and while it worked great to bring him back into work it's just not effective (in my opinion) at giving subtle aids. I've found that the cross under straps tend to stick and not flow back through the rings, maybe it's because I don't have the leather version but this is what I have found. Also my horse has gotten used to the pulling action with both reins and is no longer effective in stopping him from bucking, it's actually started to make him uncomfortable enough to want to buck.
It's a shame though because I really liked using it.
Well, Spirit Bridle does release pressure while maintaining soft consistent contact...and creates lateral/longitudinal flexion of the poll.
Spirit Bridle can also prevent rearing, bucking, but not crow hopping.
So Smrobs and Ktibb, please state your personal experience with SB and/or other cross under the jaw rein bridles.
I have twenty-two years (22), and since I created the cross under the jaw rein technology, I DO know how it works and what it will do..............
I used a Dr.Cook, but then a girl we know made a different kind of noseband so I bought a bridle took off the bit, and put the nose band on that one so you could just get a normal bridle and take of the bit too. So yeah. Dr.Cook is great as well though
