And that is a better explanation. It's a bit like "WP horses can't move out on the trail." Or "Quarter Horses can't do endurance." Rather biased and a broad blanket statement. Some WP horses can't move out due to their heavy musculature, and these are usually not the ones winning at the top levels, as you've pointed out, but ones with halter conformation that people use as WP horses at the local levels because they are easy to keep moving slow.
Arabs can't get their hind end underneath themselves? Rather biased and broad, most Arabs can but stock horses dominate stock horse disciplines based on their anatomy and warm bloods excel at grand prix dressage. And Arabs are best at endurance, with a few exceptions.
You missed my point, and you have yet to tell me how that pleasure horse, you alluded to,in that other thread, was both bred and trained
You are also confusing western pl horses with halter horses, as a good western pleasure horse is not muscle bound
I am merely telling you that when you make a BROAD statement, far as what a particular breed excels in, you look at those top open venues,m which are open to all breeds, and then see as to which breeds dominate them
Arabians have dominated events like the Tevis cup, which doe snot mean other breeds don't do well in endurance, at some level
Look at NRHA, NRCHA, NRCHA, NBHA, and look at the breed and bloodlines that dominante those events, events open to all breeds, including Arabians
Those events apy money, and those trainers will ride any horse that can win at that level
Might be easy to keep a horse moving slow, but not so much slow and CORRECT. Far as halter horses, they tend to be hot. Ever ride a halter bred horse? Halter horses at upper end often don't have their minds tested under saddle, and I can give you just a few names, of halter horses, if bred to, create not a horse that wants to go slow, but one with 'no brains home.'
I should know, as when i started to raise horses, I made the mistake of breeding to some of those heavily advertized halter horses, including Crimson War, and a horse that was Goer bred
That Crimson War stud was anything but slow or calm, nor did he have sensible mind.One foal crop, and I had him gelded
What I am saying, many breeds and good individuals can be very versatile horses, esp in breeds like the Appaloosa and Paint, where books aren't closed, thus you have a great more variety in body type, thus natural ability in specific events.
Also, when you talk about versatility, you have to ask in what time frame, and against what competition
Every event has become tougher, and those all around horses of the past, could not compete against the specialists in those events today
Many good horses can do many events,at a certain level, and that is all many people want-a horse they can do many events with
On the othe rhand, you will never see that broad spectrum of versatility at upper end, because the event is more specialized and tougher
This creates a need for both the specialist and the good all around horse-neither is better then the other, but rather serves that particular rider's goals
