A lot of horses ridden in a curb are done so without contact. So, my feeling is that she was shaking her head because she was irritated with having you in her mouth. I only think that because she is so good and kind in the halter, where it would be less offensive and she likely wouldn’t have a lot of experience to make her feel negative about contact.
So, my feeling is that maybe you should just trail ride in the halter. People ride in hackamores all of the time. If you feel you don’t have the control you might need, you could two rein her with the halter and the bridle, just leave the bridle reins hanging unless you needed them.
