The Saddlebred is perhaps THE most versatile and incredible breed of horse out there yet always seems to be frowned upon. Courageous Lord is amazing and I would absolutely love to ride him, I too ride a very game Saddlebred, although she is not quite as hot as he. The Saddlebred can compete in EVERY discipline! From the green shavings of Freedom Hall in a championship saddle seat class to barrel racing. From trails to competitive driving, they're there. In fact there was a champion 5-gaited Saddlebred, Singsation, who now is very successful in the combined driving circuit.
The Saddlebred was vital to the United States as a country, by carrying U.S. Army soldiers into battle, often being the mount of choice of generals.
As far as the complaints that Courageous Lord is not paying attention because he is not stopping on a dime, he is listening, which was described by the explanation of whoop and whoa, not to mention the adrenaline. These horses love to show, they feed off the crowd, just like when you are excited for something, it takes a lot more to calm you down from your excitement than it would if you were just sitting at home on the couch. Dr. Weaver does absolutely wonderfully!
No matter how many times you repeat it, someone always claims that Saddlebreds are sored like walkers because they step high. Look at baby Saddlebreds, they are going level from the beginning, walkers do not, that should be evidence in itself for differences between the two breeds. I'm not saying there aren't any at all, but I guarantee you will not ever see one taking a victory pass.
The tails of Saddlebreds alone are given more time, effort and care than most entire horses ever receive. Not all are cut, some can be stretched without being cut, they become flexible (like stretching your muscles properly allow you to do the splits or a back bend). Setting tails originated as a safety precaution for carriage and driving horses so that they would not be able to clamp their tail down on the reins and cause chaos. It became a tradition and touch of flair in the show ring and adds a special brilliance to the performance horses. But if a tail is not properly cared for, it's not a pretty sight.
Here's another video from Freedom Hall. A Hackney pony roadster, these too look like tons of fun!
