I just want to add in here that due to his size and previous injury I would be very weary of doing any extensive jumping with him. Maybe low level hunters but I would not gamble in the jumpers or eventing. He is a big horse, big boned and has had a knee injury. If he was a big boy with no previous injury that would be one thing, but due to the injury and his size I would not want to jump him much.
That is just my two cents on the topic.
Again he really is a beautiful boy. I would need a ladder to get on him and then would want super glue and a seat belt as I would be scared of being so high off the ground
