As far as how he rides, he's a little pokey, but he goes well with a strong leg. I jump him at 2 3", I don't know if he could go over 2 6" but im not sure. Slow trot, but really smooth canter and is very honest to the jumps, only bucks when hit with a crop. I was thinking 5K? I really have no idea though. Ps- I've been riding him for 3 years and he's never had any bad healthy problems or lameness issues. Thanks!
