Do we ignore the fact that from what I understand at home the mare seemed happier in this bit? In other words, it is not so much fixing a bitting problem with a harsher bit but changing a bit to see if something else makes the horse happier. I read it more - since I messed up the curb chain the bit was not reacting how I expected it to and I was getting the same response I used to get with my snaffle. Not - a curb bit with out a chain is just a snaffle. Being an overweight middle aged rider who is progressing very slowing on my pony because I have some fear issues means I will never be critical of someone taking the slow progression. Heck, this is a hobby. If we (general anyone) want to get excited because this week at lesson we actually managed to make one round circle I do not see how that is doing anyone else any harm. I am happy with my progress, my pony is fine with my progress and my trainer will go at whatever rate makes things work for us. That is how hobbies work...even more so as a middle aged overweight rider like me. Edit to add - That slow progress does not mean my trainer is not a good trainer. To me it means my trainer is a great trainer. She is training the horse/pony in front of her, not to some magically pre-designed schedule made by someone else.
