Well after spending most of my summer working with Arabians and having the chance to work for someone with incredible depth of knowledge of Arabians and showing, I have come to the conclusion that they are an incredible breed, capable of any dicipline.
I can't decide if I love them or hate them, it really seems to depend on the day. They seem to be highly intelligent, fast learners and have moments of pure brilliance. They also seem to be more reactive towards people I.e. They form stong opinions of you, whether they are good opinions or bad.
Personally, I think an ideal mount could be Anglo-Arabian - just enough Arabian to produce the beauty and intelligence with a bit of TB thrown in for added athleticism and to tone down that intelligence (I don't appreciate being out smarted by a horse ).
And here are some pictures of the horses I have been working with purely for viewing pleasure (the greys are all different horses, they just look similar).
