I would never breed to Titan C. I haven't heard horror stories about him, but he is a Bey Shah grandson. Bey Shah tended to be bred for halter horses. The most athletic ones would do maybe Western Pleasure. Padron while athletic, was not happy under saddle. He was trained EP but never shown because of his attitude under saddle. There are many reasons that could be, but it's not something I like in a horse.
The black one, has nice usable lines.. but they are pretty far back. Mostly looks like he was bred for color. The SE I don't know.. something looks weird, but I can't put my finger on it. The colt is probably the nicest of the bunch.. but a terrible photo to judge him by, and a bit hodge-podgey in breeding. Not sure why they bred him.. what the goal was.
Have you looked at any of the proven performance stallions? There are a lot out there that are proven in performance and are pretty.
