I have a decent budget and am looking for a prospect (probably a 3 year old, or a 4 year old that got a late start) that has the attributes to go far. Of course, a horse has to do it to prove it, but I need to prioritize the importance of traits. I certainly expect any serious prospect to be interested, interactive and inquisitive. And have conformation that will not prevent him/her from physically moving up the levels (good legs, balanced body and neck)
Beyond that:
I figure that an incredible jump should be the priority. If I can only see a video of a horse lunging and free jumping — I have to take some things on faith (like the ability to collect, bravery and the desire to jump clean).
My thinking is that, as long as the horse is naturally balanced, dressage can be taught, but the other 2 phases involve jumping. So a big jump with a powerful hind end that really flips up over the jump is all important in a horse who might go FEI one day.
Am I thinking along the right lines?
