BTW, FWIW, Master Imp has all three of the foundation sires on the first page.
The bottom side of Pointilliste is absolutely gorgeous for sport. It could hardly be better. Tail female to Ballynash, who is also the dam of Mourne and Monteval, and thus doubled in Laudanum. Alydar is famous here for jumpers–probably his most famous was as grandsire of a full TB showjumper named Dark Grey (Show name Bradford) who was a speed horse for Richard Spooner.
IMO, Storm Cat is pretty much a bust as a sport horse line, but as he gets farther back and is diluted (especially in temperament), he’s starting to show up a bit. Giant’s Causeway has a pretty nice damline for sport, though. Rahy is also a bit of a bust at this point in time, but Glorious Song is one of the best damlines in American TBs, and Blushing Groom is excellent (and has Wild Risk as damsire, which is a GOOD thing) and he’s tail female to Emali, which is also excellent (Dam of Aberali; and her daughter Aimee was a very good broodmare.) Mariah’s Storm was a good race mare and has been a good broodmare, since she is the dam of not only Giant’s Causeway, but his full brother Freud. The Roberto daughter Immense is also the dam of a pretty good sire named Panoramic who has sired some chasers.
Storm Cat’s dam has Spy Song and Bolero, both lines which fairly reliably produced show jumpers back years ago. Secretariat has some sport presence, as he should with his sire and dam. First Rose comes from generations of good and quality broodmares. Crimson Saint was also the dam of Pancho Villa, Terlingua’s full brother, and Royal Academy who is the sire of Painters Row. She was a good broodmare and dam of broodmares. Papila was an excellent influence for soundness.
One thing about Storm Cat is that he was himself and sired chunky horses–close coupled and muscular. Giant’s Causeway fits that description and is very downhill to my eye. This is a sprinter/miler line primarily, although Giant’s Causeway was able to stretch to 10f for the Breeder’s Cup Classic. Which is not necessarily bad because jumpers need short twitch muscles. But they also don’t need modern American sprinter conformation of the QH type.
A Chieftain daughter was dam of Shaab.
Giant’s Causeway is still so good/hot as a racing sire that almost none of his direct get have made to sport; and his grandget are still rather young. But he too has no presence in sport.
In this case, it would depend a lot to me on whether Pointilliste took after his sire or dam, his other foals and the dam. To put it bluntly, my thought would be a resounding “maybe”, tending toward a “wait and see.”
