You seem very interested in spanish breeds. Have you tried looking at an Azteca. Its a newer breed that is kind of common around where I live. Theyre bigger and thicker than the breeds you chose so they are hardier. However they still have the big flashy gaits. I would watch the type of horse you get however. Horses like these and arabians can be VERY touchy and a new or inexperienced rider, or even just a rider who doesnt suit them can ruin them very quickly. I generally consider QH's the best kind of horses to start with because theyre calm and generally forgiving. And when you feel your as far as you can go with the QH, with professional opinions then you might be in the market to look for a bigger flashier horse.
