what a great fun demonstration! I think the main thing that stood out for me was how much more relaxed the little QH. OK he was as flashy (except when he spun!!!) or had the extravagant gaits but he seemed to be ridden with very little aid and very quietly.
I also liked how fundamentally the riders produced the same results although I think the western riding got better results from the dressage horse than the dressage rider got from the QH. Must have been really interesting to try both types of riding/horses!
