I have a great show jumper on my hands: On a lunge line, she's jumping 5 feet, no problem, no sweat. She's a 15.3 SaddlebredxCleveland Bay mare, with thick legs, a long scopy back, long leck, and powerful hindquarters. She will litterally jump anything you throw at her.
Her problem: She has no head collection whatsoever. I do not ride her in a martingale, and I haven't entered her in a show before. When she gets nervous or excited, her head will go way up, but not straight up, as a lot of green arabs and morgans do. When I ask her to lower her head, she looses her power over jumps and is more likely to knock a rail.
For shows, should I just let her keep her head up if it will give us a more likely win?
