Honestly if she goes better bitless, I would stay bitless. I dislike bits in general but I recently got a mare who had been trained In a snaffle so I bought a snaffle for her, rode her twice in it and she was nervous, wound up, fussy, would do nothing but backup endlessly with even the slightest bit pressure (a mixture of nerves, being green, and discomfort caused by the bit) and I could do nothing to get her to calm down and pay attention to me. So I tried ridge her in a rope halter and clip on reins, she was a completely different horse, she learned a ton more, paid attention to me, and was visibly 100% calmer than the other two times. In my experience horses almost always dislike bits (I don't blame them). I'm sure there's horses who need bits/ like bits but for me I prefer to ride bitless especially when they do so much better that way. However I understand that many people need more refinement from their horses so I am inexperienced in that way.
