Ok, so, I'm planning on teaching my Tennessee Walker saddleseat sometime in the near future and I'm not sure which bit I should use. He's currently in an Eggbutt Snaffle and my trainer wants to switch him to a Wonder Bit in the future once we're done with this particular thing we're working on. I've heard a lot of negative press about this bit, so I'm not sure. My friend uses a bit on her show Walker that . . . Swivels . . .? It's kinda hard to describe. It look like this:
Can anyone tell me what the name of this bit is and more about it? Also, any suggestions on bits?
