Going to agree with Maura here (I think I usually do). Lower level eventing is all about the dressage. You want a horse that is capable of scoring low 30s/upper 20s if you intend on being competitive each time you go out.
Personally I don't like judging babies conformation because I've seen some butt ugly babies grow into rather nicely conformed adults. He's cute, and will certainly draw some heads. But I don't like the front end movement. It really doesn't reach forward.
I'd be interested in seeing the updated vids... though I think I'll feel the same. He might be a decent low level eventer, but IDK.
