Totally agree with your point about some horses responding better to certain drivers Tyson, there is no doubt in my mind that is true of some horses and then there are some others you could just about put a bag of chaff in the bike and they'll go just the same.
I'm not so sure about the point your making with Vegas Bound---he is definately NOT a bag of chaff type horse, but I think ( from observations only) he might not be the easiest horse to train. Having said that it appears he may have found the "class barrier" as well to a certain degree.
He had a beautiful trip last night.
