Hmm interesting idea. I don't know too much about the draft crosses... I want something that will be very competative in Hunters & Jumpers that is of modern type. Will the draft blood not make him/her too "heavy?" Would the offspring be atheletic enough for jumping 3'9" +? What are the popular draft stallions out there these days?
Your guy sounds very cool though. What do you plan to do with him? Post pictures!
