Well, Reputed Testamony and Loyal Pal both are recent enough that they should still have offspring competing. That means that you could do what would undoubtedly be an incomplete sire search at USEF for offspring and actually be able to see competition records–which would be a huge bonus.
For Epic Win I went to the site that I use for FEI results–and I admit that they don’t have complete records for horses that old, but they do have all of the Olympic games, WEGs, World Championships, Badminton back to 1946, and Burghley back to 1961. I don’t think that they include all starters; maybe just the top ten or twenty. But they don’t have Epic Win in their database at all, either for himself or in their pedigrees. (That’s why I like this site because they do have pedigree information, so you can get both progeny and results–and the progeny’s results if they had any. It covers many generations). None of Denny’s stallions, old or new, are in that database.
I do know that Right of Light was the sire of King Oscar, who was a successful event horse for Denny, I believe–but Right of Light is not in the database either. Epic Win also evented with Denny, IIRC, at very high levels, but I can’t find any reference to his get doing anything notable. If any one has info on Epic Win get in sport, that would be extremely helpful. Level, in particular.
IIRC, I did some research on Caro, and Loyal Pal didn’t show up as a very successful sire for sport. The best Caro son was With Approval.
If you put the mare in the Sport Horse Breed Database, you can get a five generation testmating.
I just remembered something. Years ago, I downloaded some old USEA records. If I can find them, I’ll look around to see if they have anything useful.
I’d really like to pimp Right To Light. He’s got Court Martial sooo close, and was an excellent racer with 65 starts, 12 wins and 17 places, and won at age 8. I think that says a lot about his athleticism and his soundness. He’s actually sired a performer in FEI level sport from very limited opportunity. He’s even got multiple lines to Roi Herode back in the engine room, along with quite a lot of Hampton through Bay Ronald, Ayrshire, and Ladas. He’s also got more than a little to Lady Josephine through both Mumtaz Mahal and Lady Juror. Macherio was the tail male grandsire of Angelo xx, a very productive line for German WBs in FEI sport, mostly in dressage. In fact, it’s one of the greatest in history, IMO. Sire of Ahlerich and Amon, damsire of the Rubensteins and Rembrandt. The line is starting to produce jumpers and eventers.
He’s described as a light chestnut with white mane and tail, not that you care about color.
