So, I am through and through an eventer. However, I did begin my riding career at a hunter barn and have temporarily returned to one at the moment. I've showed a few times and placed quite well in the hunter ring, but was really too young at that point to ask the whys of things.
At this point in my life I am very interested in the theory behind riding and not just the mechanics. I have invested quite a lot of time into learning thoroughly about the reason for different styles and ways of riding in eventing, and have also gotten into and learned much about dressage as a discipline itself, not just as part of eventing.
So my question is this, in dressage it is stressed that the rider maintain a deep independent seat in order to drive the horses hindquarters and encourage correct impulsion and such. This is also somewhat important in show jumping so as to make it over those higher jumps. Am I right? So if this is the case, then why is it hunters are told to lean slightly forward? Especially in the canter. It seems to me to go against what riding theory I know, and also seems as though it would put you in a more likely position to take a spill if your horse spooks sideways or balks. Could someone please explain? Thanks!
