Thanks for the analysis Beowulf. Can you provide a little more information about the too-far-forward shoulder/forearm? A quick google didn’t lead to much clarity on it. How is this evaluated? What are the effects on stride length and/or jumping ability? I think Spaniard’s shoulder slope/angle/conformation looks pretty good. What am I missing?[/QUOTE]
A more forward shoulder, with forward fore-arm placement, in my not-scientific and purely-anecdotal experience, makes a top-heavy horse. It makes a horse that has a precocious stride, but a horse that is predisposed to be on the forehand and downhill.
I call this look the “Drumstick shoulder” - because to me, that’s what it looks like.
For racing, this is good – while the driving power comes from behind, you’ll notice that successful sprinters tend to have this type of conformation. The forearm is relatively short (and the humerus even shorter) and the cannons long[er] – this type of conformation is suited for speed, and is likely the result of breeding for speed. The elbow in horses with this type of conformation is much more forward placed than in other horses – and as these joints get ‘closer’ together, the length and slope of the shoulder is affected to the point where you have a straighter shoulder, shorter forearm, shorter/upright humerus, and lower and more forward placed elbow.
Jumping requires a different type of conformation, different twitch muscles, different effort - a horse bred to jump usually has a longer forearm, shorter cannon, longer humerus, steeper slope in the humerus, angled shoulder and an elbow that if you dropped a plumb line from the middle of the withers down, would line up with the middle of the withers.
I would not personally breed to a horse with Spaniard’s conformation if I was pursuing sport. He is very much a sprinter type. Nothing wrong with his conformation from a racing standpoint, but it is not the conformation you need for sports like jumping & dressage.
If I were looking for a race-horse TB for sport potential, I would obviously go with a TB that has been proven in sport: Sea Accounts, AFR, etc.
However, if you are looking for a RACE HORSE TB, here are some examples of TBs that I think have the conformation (and pedigree) needed for sport pursuits. Conformation isn’t everything, but it’s a start:

Majestic Warrior (a little too straight behind for my preference, but excellent sporthorse movers):
