Lexus Kody is no joke. He's a huge animal with a flawless gait. I haven't followed his whole career, bur peripherally I wasn't sure if he'd handle a flat half, and he clearly did.
Burke's didn't develop him. No surprise there; he has the owners to back up buying for this level.
I'm no fan of the Burkes. I think they couldn't give a shit about the welfare of any horse in their string. But they sure can keep one "sound" and going. And have the money to buy when they can't produce their own.
