As a long time dressage rider I've had the whole "You should never see your toes infront of your knees!" thing drilled into me. Yet as I find myself moving into eventing I see quite a few very good rides who adopt a chair seat for their cross country phase. (Many of them have a slight chair seat in dressage and jumping phases too)
One of my friends is an endurance rider who also does some very scary trail riding. She rides in an Austrailian stock saddle with a definite chair seat. If she can post in a chair seat for 100 miles and pass every vet check, is it really that hard on a horses back? (When done well?)
Would love to hear people's thoughts on this. Do you ride shoulder-hip-heel or with a forward leg? What discipline? What do you think are advantages or
Disadvantages to either style?
