Pumpkin is comfortable with a rider, he just prefers to do what he wants. As for the jumping, Pumpkin can clear high poles, he is hardly trying when being jumped at the moment. I can see your point though, but me as Pumpkins owner, I know that he is ready to be a little more challenged. Chingaz is just teaching him some manners under the saddle. From where I stand and watch Pumpkin being jumped, he can go a fair bit higher. He is confident at the hights he is already jumping.
