You really have to be careful when you are buying a horse for a kid. Make sure it is safe safe safe!!
High Five is young, not going in the double, doesn't collect properly and looks like he is bullying his rider around, especially in the contact. He is a 2003?? Like my boy, they are in a really delicate part of their training at this point. They are learning so much about collection and their bodies are changing so much that to put a kid on the horse is asking for trouble. I would pass on this horse and leave it for a professional, unless you are working very closely with a very good coach and trainer that can ride the horse at least 2 times a week and have your daughter in a lesson every other day.
Ravelisko is much older, so you are playing with fire a bit in the soundness department. BUT I think this horse is waaaay more suitable for a junior. He is going in the double already, and does all his tricks without fuss although he is way less flashy about it. He is content in his work and knows his job. He is trotting around like a pony club horse but I imagine if you get an effective rider on him, he could have legs flying all over the place.
I would go with Ravelisko on the condition that he passes a PPE with an FEI veterinarian. I would also recommend looking for nothing younger than 8 (2002). And it always helps to have an experienced broker, or your coach at least helping you look for a horse. Also remember if something seems fishy, it is fishy and just walk away. If anyone tries to pressure you into a sale, walk away.
