I used to show Apploosas and competed at the national level. I had a 3 YOSB HUS gelding that was foundation bred (Rustler Charger) to be a western horse. Based on his bloodlines, he should have been born a 15.2 working cow horse, with potential to excel in halter, reining, roping - you get the picture. He also had some Bright Eyes Brother in there, who was a foundation and Hall of Fame Appaloosa stallion from his performance in the halter ring. He was also known to be handy working with cattle. From his pedigree, this horse should have been a handy little western horse.
His breeder was quite surprised when at 2 (I don’t agree with starting 2 year olds but this is what they did) the horse was so incredibly tall and long-legged that they couldn’t ride him in the roundpen - they had to ride him outside the roundpen. He was a huge, elegant bay hunter. None of them expected this, and they sent him to a trainer and enjoyed their new journey into hunter under saddle classes. The working cattle horse-bred gelding turned out to be his most successful horse, winning a national championship, year end awards in multple HUS divisions, futurities, you name it.
It’s a good thing the trainers didn’t look at his pedigree and instead chose to look at the horse for what he was and what he could do. Had everyone looked at what he was supposed to be instead of what he actually was, the opportunity might have been missed.
Now I ride hunters and I love how a nice horse is a nice horse. You don’t ride the pedigree - you ride the horse. I like that the names aren’t over the top silly trying to pay homage to every horse in the line, and that it truly is about the horse’s performance.
If I owned mares and was looking to have a breeding operation, I’d likely pay more attention. But as I tend to end up with geldings, it really doesn’t matter so much as there is no future for the bloodline in the horse I own.
