I am no expert in Saddlebreds, but there IS a reason so many breeders are choosing to crossbreed Warmbloods. A few posters in this thread have made comments about the mind - the Warmblood is bred to be a supreme athlete, to be sure! But like any supreme athlete, they are a bit of a diva. Many are either (a) stubborn or (b) hot and reactive. And sometimes a and b! So for the average rider, they are not an easy or fun ride. How may average riders (be they AA or lower level Trainer) can bring along an athletic WB without the help of a better rider? Of course the flip side to that - more WBs are in pro training then most other breeds, which helps them up the levels.
It is kind of like watching the Olympics -so may of the top athletes are a bit “lacking in social graces”.
The average rider wants a horse they can ride on their own - in most cases, budget restrictions dictate that they buy a horse that doesn’t require full time training. Hence the desire to crossbreed. And the popularity of USDF’s All Breeds program!
Add to that - the innate soundness of some breeds that just doesn’t translate to the WB. I can’t tell you how many people I know who have a WB and another horse - and consistently, it is the WB who is lame or off. Torn suspensory, pedalostitis, meniscus strain, SI strain, kissing spine, the list goes on and on and on. And as a small-time breeder of WB CROSSES, I get the story from about half the people who contact me - I want a cross, my WB isn’t sound. And - I’m tired of fighting with my WB.
I have great respect for the WBs and the trainers and riders who bring out the best in them, but I also desire a horse who is just more into people, who has a desire to please, who is sensitive but safe. And who stays sound.
I also recognize that MOST RIDERS are not headed for the top - they are middle income (and often middle age) AAs, lower level Pros, Juniors without wealthy parents - and they want a horse they can ride, have fun on, compete locally and regionally, perhaps make it to the mid levels or dip their toes into FEI someday. And they don’t have the big $ to buy the top quality WBs - and the “culls” are culls for a reason - they are stubborn, or difficult, or they can’t move, or they are lame. And that is not what your average rider wants or needs, and that is why some breeders are cross breeding. I don’t breed for jumpers, so I can’t really comment on that specific discipline, although some of my crosses are jumping and eventing, and doing quite well.
I consider “quite well”, as a young horse that is in the top 3 in regional and local competitions, top 10 regional championships. They are beating WBs, and clinicians are commenting very favorably on their athleticism, honesty, and work ethic. Their riders love them. I consider that a successful breeding program. I’m not breeding for the Olympics. I do use bloodlines that are capable of upper level work - there is a difference between a horse who can do GP and a horse who can compete at WC, WEG, Olympics. And competitive at shows - any horse can do lower levels, but not any horse can be competitive. And there is a huge difference in the rider who can train and compete that way too!
My point - educated cross breeding is not a bad thing. Breeding for the average rider is not a bad thing. But - having said that - you must be educated, you must understand bloodlines and genetics, and you must be willing to put the money and time into raising these babies correctly. The average rider does not buy a foal - they buy a horse who has 6 months to 2 years of training - which means you commit to getting your horses started under saddle and going well. It is not a commitment to enter into without thinking about the long term side of it.
OP - COTH Breeders Forum has always been focused on Euro lineage WBs - I seldom post here because of people like Bayhawk - the lack of common courtesy and respect is very sad. There are some wonderful knowledgeable people on this board, but the message delivery isn’t always so great, especially when some of the arrogance starts to spout. And it is even easier to be so unpleasant when posters don’t use a real name and have a weblink to people know who the person is. And it is a “breed” biased forum, which is why you don’t see many non-WB people active here. Yes, there are plenty of people who are breeding non-WB (or WB cross) sport horses, but they tend to avoid a forum where their results are always going to be called “inferior”.
