The first horse has a LS joint that is good, it's directly above his point of hip. The second horse it's hard to tell because of the photo but I'm guessing it's behind the point of hip, not good. The third I'm also guessing is behind. The fourth I think is also behind.
So am I right? Or wrong? Where is their LS joint positioned? I'm looking for a jumper so the LS joint placement is critical.
