Okay, so I am starting to train a pony that was used for pony rides and has been a pasture pony for years. Im training for western, but have no past knowledge on what bit she prefers or if she was even ridden with a bit. I have to buy a new bit since I only have 5" bits and she takes a 4.5". Where should I even start? What bit is a go to and a good starting point? Thanks!
