This is a good pedigree, but not for dressage movement, in my opinion. This is a pedigree for an eventer.
I don’t know if you would have dressage movement with this horse. You would definitely have jumping ability. It’s nice to see Lost Code up so close, relatively speaking. He is almost always buried in the back… but that was a stallion that made very hardy, enduring horses. It’s a shame he was not more successful in racing progeny, because I found his offspring to be wonderful with good temperaments in their second careers.
Speightstown has some good looking horses near me. I notice they tend to be more compact, decent movers, great jumpers. A little spicy. That comes from the Gone West, btw, not the Storm Cat. Storm Cat will give you lots of athleticism and no bottom. We’re quite far back now, though.
All of the stallions mentioned above, have average movement in terms of dressage. SC made some very dressage-moving sons, though (Giant’s Causeway, for example).
What’s better is the Honor And Glory and Relaunch (In Reality). This is a proven line for eventing, and a good line for dressage. Honor And Glory in my experience made substantial, good minded horses. It’s a shame he was not used more often in sport-breeding. In my experience this line is good moving, very nicely conformed for sport, and excellent jumpers. And sound!
