“You people” would be me. And I can’t tell you just how it makes me feel to be belittled, called ignorant and uneducated for an honest error. Not one of you people had the grace to correct me politely.[/QUOTE]
Don’t worry about it too much. People get excited when pushing their opinions around and tend to trample others in the process. I enjoyed your posts and if you make a mistake, so what - everyone does 
We run an American Saddlebred stud in Australia with the express purpose of producing light horses for competition. The oldest we have right now is about to go under saddle so nothing performance wise yet, but I wanted to add to the discussion as our purposes are relevant to the OP’s post.
There is no question that the American Saddlebred is not as easy a task to develop for dressage in the body as most Warmbloods.
However there is also no question that the American Saddlebred is an incredible horse for the non-professional to ride and work with. Their willingness to work, forgiveness of errors and ability to quickly change wrongly taught things into the right form makes them absolutely fantastic to anyone learning to go up the levels with one horse.
I’ve worked with them for nearly 20 years now and find them an absolutely joy to deal with. That’s why we own and breed them for others to experience how fantastic they are as a saddle horse. It’s not the physical ability or the little shortcomings to be conquered, it’s the outstanding mental attitude that gets you over the line. They just handle everything. It’s fantastic.
I’ve attached a few snaps of our breeding stock for the OP, to see the type we are selecting for breeding for dressage and eventing. OP, if you would like bloodline details (most have recent imported lines and would have similar readily available in the USA) please let me know.
The black mare is one we are considering crossing to WB, if it doesn’t make her too coarse.
