1) About her bit, when I bought her she came with her swivel curb bit. I am a little concerned that keeping her on this bit while riding her English with rein contact is not going to be good for her, or me. I have a very nice eggbutt dee snaffle bit with copper mouth that I think would work better for her with the greater contact. What do you think? What is a good way to acclimate her her to this type of bit and how it is used?
