Wow - I definitely came to the right place to ask for information!

She played polo for the past 10 years, she has never been raced. Your comment about bracing against the bit is dead-on, that is what I'm seeing with her.
My thoughts had been to start her out with a bit similar to what she was accustomed to, and then work up from there. However, after reading all of the replies and researching on my own, I think I'm going to defer this one to our trainer. Our work schedules have conflicted lately, so I may be too eager to get started on this. I believe I'll discuss my thoughts and your recommendations with her when we get together next week and move forward from there.
I'm absolutely thrilled with the amount of information you have all provided! Thank you SO much!
