Brent...check out his video here.
http://youtu.be/mXklbhXuUNk I saw him in Denver, and he was impressive. For an older bull, he moves well and is really massive. Still enough size and grow to him. If i remember right, they bought him as an older bull from a commercial ranch in Canada, and they are now just getting the first calves born here in the states to him. If you wanted to protect him, maybe use him on some really feminine fronted made cows...as he's a little deeper chested and has a little bit of leather up front. But that's to be expected for the power bull that he is. The Patron bull from Argentina they had on display was also really impressive!! Hope it helps...
