Yeah, a few other people ride her and have the same issue. I keep my upper body very tall and don't lean forward. (Being an Arab she is sensitive to pretty much all movement, leaning forward to her, even just a tiny bit, means 'run as fast as you possibly can!' oh that silly girl. Like I said, we're working on it.) She is still fast on the line, but doesn't seem to be more fast to the right. Which is fine, I lunge her to get out the excess energy so she doesn't go all crazy on me, haha. I just am not sure what other tricks/tips to try to get her to slow down. The circles seem to help, but lately she's a bit quick in those too. :P
