Well that makes sense as to why she wants to keep her head so high if she was trained to do so as a racehorse, then that idea was reinforced by a saddleseat bit. I feel like the longer I ride her, the more relaxed she gets and she puts her head slightly lower.
Here are some videos of me riding her. Feel free to pick apart the way I'm riding her, or my position, or whatever.
These two videos are from the fourth time I rode her, just before I decided to buy her. Before I started riding her she had never been asked to canter really. The girl who had her for a few months before me would just run her - in a saddleseat bit. She was a brave, brave girl, in my opinion and most any other OTTB would have seriously injured her, but my girl is remarkably tolerant.
I know my leg swings/bobbles, and I have a bit of a chair-seat going on. I have a lot of leg, but that's no excuse. I let her go on a bit of a looser rein because I was still getting to know her.
This was probably her second time cantering, which is why she kind of runs into it. She greatly prefers her right lead, which I find strange.
This was at her first show, ever. I didn't get to ride her for two weeks leading up to the show (I go to college and she lives at home), and so we literally pulled her out of the pasture after a two week break, I got a five minute warm up, and then we went into our first class.
During the five minute warm-up, we cantered our first jump, ever. I had trotted her into a few cross rails and small verticals and cantered her out, but never cantered a jump with her. So, keep that in mind.
